But a great Lord, a wicked Man, is a terrible thing.
[tr. Clitandre (1672)]

If a great lord is a wicked man it is a terrible thing.
[tr. Van Laun (1876)]

But if a great lord is also a wicked man, it is a terrible thing.
[tr. Wall (1879)]

But a wicked nobleman is a terrible thing.
[tr. Page (1908)]

But a great lord who is a wicked man is a terrible thing.
[tr. Frame (1967)]

But a wicked nobleman is a frightening master.
[tr. Bermel (1987)]

But a great lord who's a wicked man is a frightening thing.
[tr. Wilbur (2001)]

O you habit of sinning, what delight you afford to the wicked and the audacious, when chastisement is afar off, and when impunity attends you!
[tr. Yonge (1903)]

Alas, the habit of evil-doing! what pleasure it affords to the depraved and the shameless, when punishment is in abeyance, and has been replaced by license.
[Source (1906)]

Men may commit injustice, because it is in their interest to do it, and they chuse rather to satisfy themselves and others. It is always with an eye to themselves that they act: no body is wicked gratis: he will have some reason to sway him; and that reason is always a reason of interest.
[tr. Ozell (1760 ed.)]

Men may do injustice, because it is in their interest to commit it, and because they prefer their own private satisfaction to that of others. It is always with a view to themselves that they act: nobody is wicked for nothing: he must have some reason that determines himl and this reason is always a reason of interest.
[tr. Floyd (1762), # 83]

Men act unjustly, because it is their interest to do so, and because they prefer their own satisfaction to that of others. They act always to secure some advantage to themselves: no one is a villain gratis; there is always a determining motive, and that motive is always an interested one.
[tr. Davidson (1891)]

Men act unjustly, because it is their interest to do so, and they prefer their own satisfaction to that of others. In acting they always have in view the effect their action will have on themselves: no one is bad for nothing; every one must have a determining motive, and that motive is self-interest.
[tr. Betts (1897)]

Men can commit injustices, because it is in their interest to do so, and they would rather satisfy themselves than others. It is always through thinking of themselves that they act unjustly; no one is gratuitously bad, there must be a reason which determines the act, and that reason is invariably one of self-interest.
[tr. Mauldon (2008)]

Men are capable of injustice, because their self-interest leads them toward it, and because they prefer their own satisfaction to that of others. Everything always revolves around themselves. No evil is ever done gratuitously, for there is always a reason behind it, and that reason is always one of self-interest.
[tr. MacKenzie (2014), # 83]

Now he is the basest of men who practises vice not only in his own person, but towards his friends also; but he the best who practises virtue not merely in his own person but towards his neighbour, for this is a matter of some difficulty.
tr. Chase (1847), ch. 2]

Worst of men is he whose wickedness affects not himself alone but his fellow with him; best of men is he whose virtue affects not himself alone but his fellow with him; for such a one has in all sooth a hard task.
[tr. Williams (1869)]

As then the worst of men is he who exhibits his depravity both in his own life and in relation to his friends, the best of men is he who exhibits his virtue not in his own life only but in relation to others; for this is a difficult task.
[tr. Welldon (1892)]

Now the worst man is he who exercises his wickedness both towards himself and towards his friends, and the best man is not he who exercises his virtue towards himself but he who exercises it towards another; for this is a difficult task.
[tr. Ross (1908)]

As then the worst man is he who practises vice towards his friends as well as in regard to himself, so the best is not he who practises virtue in regard to himself but he who practises it towards others; for that is a difficult task.
[tr. Rackham (1934)]

The worst sort of person, then, is the one who uses his depravity both in relation to himself and in relation to his friends, whereas the best sort is not the one who uses his virtue in relationship to himself but the one who uses it in relation to another person, since that is difficult work.
[tr. Reeve (1948)]

The worst man, then, is the one whose evil habit affects both himself and his friends, while the best man is one whose virtue is directed not to himself, but to others, for this is a difficult task.
[tr. Apostle (1975)]

So the worst person is the one who exercises his wickedness towards both himself and his friends, and the best is not the one who exercises his virtue towards himself but the one who exercises it towards another; because this is a difficult task.
[tr. Thomson/Tredennick (1976)]

So the worst person is the one who exercises wickedness in relation to himself and in relation to his friends, and the best is not he who exercises his virtue in relation to himself but the one who exercises it in relation to others, since this is a difficult thing to do.
[tr. Crisp (2000)]

Worst, then, is he who treats both himself and his friends in a corrupt way, but best is he who makes use of virtue not in relation to himself but in relation to another. For this is a difficult task.
[tr. Bartlett/Collins (2011)]

For what is more unsuitable to that high Character, than for you to think any thing worse, than dishonour, scandal, baseness? to avoid which, what Pain would not only not be declin'd, but also be eagerly pursu'd, undergone, encounter'd?
[tr. Wase (1643)]

For what is so unbecoming? What can appear worse to you, than disgrace, wickedness, immorality? To avoid which, what pain should we not only not refuse, but willingly take on ourselves?
[tr. Main (1824)]

For what is less worthy than for anything to appear worse to you than disgrace, turpitude, wickedness? which to escape, what pain is to be refused, or rather not to be welcomed, sought for, embraced?
[tr. Otis (1839)]

For what is so unbecoming -- what can appear worse to you, than disgrace, wickedness, immorality? To avoid which, what pain is there which we ought not (I will not say to avoid shirking, but even) of our own accord to encounter, and undergo, and even to court?
[tr. Yonge (1853)]

For what is more unworthy than that anything should seem to you worse than disgrace, crime, baseness? To escape these what pain should be not only not shunned, but voluntarily sought, endured, welcomed?
[tr. Peabody (1886)]

There is nothing more unworthy than for you to think anything worse than disgrace, criminal behavior, and infamous conduct. In order to escape these, any pain is not so to be rejected, as to be actively sought out, undergone, welcomed.
[tr. Davie (2017)]

To expose vices to the ridicule of all the world is a severe blow to them. Reprehensions are easily suffered, but not so ridicule. People do not mind being wicked; but they object to being made ridiculous.
[tr. Van Laun (1876)]

Displaying vice to mockery of men deals it a great blow. Men will put up with admonition but are loath to be mocked. One might be willing to be wicked; one cannot bear to appear foolish.
[tr. Steiner (2008)]

Capitalism is the astounding belief that the most wickedest of men will do the most wickedest of things for the greatest good of everyone.

The great merit of the capitalist system, it has been said, is that it succeeds in using the nastiest motives of nasty people for the ultimate benefit of society.

Capitalism is the extraordinary belief that the nastiest of men for the nastiest of motives will somehow work for the benefit of all.

Misunderstandings and neglect create more confusion in this world than trickery and malice. At any rate, the last two are certainly much less frequent.
