You know, I think a lot of times what happens when we as actors know we're playing a bad guy is we get into bad guy mode. You know what, man? In real life, bad people do good things too and good people do bad things. So you don't necessarily have to be the stereotypical bad guy to still do bad things.
My entire life, I've always known that I wanted to be a performer, but I didn't know exactly how, where or when. I never learned or studied the craft, formally. I grew up doing martial arts and playing piano. But, something inside of me always said that I was going to do this, as far back as I can remember.
