Sigh.. Must i really do this?

Did i did something wrong. Or should it be right? What if... I can't imagine what will happen next. I am partially involved, but.... Is that call blaming? Or sabotaging? If i was really caught, what will happen? Even if i dislike that person, i don't think I should do that to her/him. Am i too rash? Should i report that it is just an misunderstanding. or should i just wait for the result?? If her/him really got punished, i believe i wouldn't feel good either, even though i don't like her/him. I really can't imagine what will happen next. In fact scared to take the next step. it shouldn't be that way, isn't it. Even though i didn't wanted it to be like this, forced by others... But i can decide myself, i make that choice, maybe i was also attempting to plot her/him. I was in greed. Is that vicious?? I should set an example. I actually don't really mind about that action, why should i just spread it? I think i made the wrong decision to tell her/him. Someone please please tell me what is the next decision. I am really confused, vexed out...
