Because it can cause a lot of trouble for you later in life. You could end up seriously hurting or even killing someone. Not a good life plan if you ask me. It's ok to feel hostile though. I feel hostile a lot towards law enforcement for something that happened to me when I was younger. But you have to subdue it or try to tone it down. Just Act. If it saves from getting busted, then fake it as if the world was ending.
