Sometimes I can't help but feel bad for my step brother.
Why feel bad for your step brother?
I feel bad for him because I'm just good at getting out of situations.
While the reason for feeling bad for your brother is wrong, it is good that you care about what happens to him. It is good to care about what happens to your family members.
He is in the wrong way.
It is good that you are feeling empathy for someone else, but I wouldn't say he is being wrong. You're the one acting out here and he seems like he's just being stuck with what you're sticking him with. Maybe you could stop hurting him if you feel so bad about it?
