Good and bad are subjective terms. No one is 100% good or evil. We are defined by our actions and intentions. Only you know what is in your heart and how you display this to the world.
In the end, it's the heart which matters bro. Be proud of who you are. Even I'm into BM and extreme metal stuff. People do categorize me as a lunatic but you know, that's how I roll and I'm proud.
