MEDEA: Oh, what an evil power love has in people’s lives!

CREON: That would depend on circumstances, I imagine.

[ΜΉΔΕΙΑ: Φεῦ φεῦ, βροτοῖς ἔρωτες ὡς κακὸν μέγα.

ΚΡΈΩΝ: ὅπως ἄν, οἶμαι, καὶ παραστῶσιν τύχαι.]

Euripides (485?-406? BC) Greek tragic dramatist

Medea [Μήδεια], l. 330ff (431 BC) [tr. Vellacott (1963)]
    (Source)

After Creon has spoken of how both love of his country and his children requires him to banish Medea. She has already faced Jason's love gone wrong as well, and her reaction to that will give end up in bad circumstances to all involved.
