Thanks for realizing that just because he was an asshole who cheated on you, he didn't deserve to die for it.

You killing him was borne out of your love for him and don't let people convince you otherwise. You know this reminds me of a quote from Sarah Waters' Fingersmith:

>And so you see it is love—not scorn, not malice; only love—that makes me harm her, in the end.

​ Had you not he'd have suffered. Be happy that you were able to love, the Jimmy you loved never cheated on you, he wasn't the one who bit Mike's head off. That was someone else altogether.
