Damon
You didn't have to ask him, he's Stefan, he'd do anything for you. My brother is a murdering douchebag, but he's my brother and I love him and I have literally gone to hell for him. Doesn't change the fact he's a murdering douchebag.
Your problem is you don't think, you just react, and Stefan is always the one cleaning up the mess after. He's been through a lot lately, stuff you can't even begin to imagine, so he doesn't need you dragging him down.
