'Eye for an eye' is nothing more than a buzzword used by people to justify and legitimise taking the most expedient option while still seeming like a better person.
Contrary to popular belief, lex talionis (ie. "Eye for an eye") is a call for restraint of excessive punishment.
Back when the punishment for stealing was to lob off a hand, invoking "Eye for an eye" would be saying, "Did he cut off your hand? No? Well, you can't cut off his hand. He merely stole monetary sum, so you'll be compensated a monetary sum."
Similarly, when applied to this situation, "Did the rapist mutilate their victim? No? Well, you can't mutilate the rapist."
