I belive humans are capable of unconditional love. I guess it all depends on the person. Like me, my step dad is the biggest worst a-hole you could ever meet. He is'nt physicaly abusive or anything, just a drunk with a mean streak and a big mouth. He has said hurtful things to me since my mother died. I can't even talk to him becuase he makes me so mad. But do I love him? Yes. Would I help him if he called upon me? Yes. Why? Because he got my mom away from her extremly abusive heroin addict ex. He fed and clothed me showed me how a real dad can be like. He just went down hill when my mom died. He could say or do anything and I would still love him. I can't help it he's my dad.
