I know how it can get about emailing people. No worries! <3
The only thing I have is that Eve loves her son. Murdering people aside, she still gave birth to him. Can't kill that kind of love. So no matter how finnicky and angry he can get she'll always be there, trying to soothe and give him love. Because she's his mom, and it's what she does.
Also, according to some sources, it was Envy who made him kill Abel, so my little Sin is all curling like a panther and going 'yesgood', so she'll probably try and put her claws in him again.
