Dear Karma, when will you cut me some slack?

For some strange reason, my actions have great influence over the people that hang out with me. I get them into the same music, clothing, and bad habits. I don't mean to though, it just sort of happens. Once I've completely molded the person from the inside out, I assume that everything will remain the same. Pretty soon the person is acting and thinking the exact way i am and that results in disaster. Then something incredibly big happens and because I was the person that introduced the idea to him/her, I involuntarily take all of the blame for it. Then I'm suddenly this monster that destroyed this person that supposedly had a bright future. There are two sides to every story, I just wish that someone would just take the time to listen to mine.
