It's not an excuse, it's a fully-justified reason, completely valid. He does things like that all the time, finds someone who isn't in their right mind at the moment and goes off on them for no reason other than his own sick amusement. It's dangerous - he did it to me when the sins were going around. Told me to kill myself. I wasn't myself, so I listened. If someone hadn't come and stopped me, I'd be dead right now and it would have been his fault.
It's not the first morally ambiguous decision I've made, and it's not the closest I've come to the dark. I'm being careful. It was a one time thing probably, and very mild. Everyone's just... blowing it out of proportion. I didn't expect you'd do the same.
