The two brothers never feed on you, you were dear to them. Obviously they could never forgive themselves if that happens because they took care of you since forever.

You at the age of 17 have to live with them having 167 years. You the only human in their family because your parents died so your brothers always took care of you even if Damon doesn't like to show concern for you, he'd kill anyone that hurt you.

Lately with the originals back in town, the fights, it was horrible.
