In games with a karma system, which role do you usually play? Good or bad guy?

I try to play it straight down the middle. Which most games like this don't really let you do in the long run. Though I find that makes game endings really gripping. I'm so undecided about my character's morality that it makes my choices more compelling.

KOTOR was the longest I got with this. Up until the very, very last mission I was neither good nor evil.

Fallout 3 I didn't like as much because it forced my hand too early.
