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

If it's clear-cut, I'll pick the "good" path, then possibly the "bad" path if the paths are distinct enough to warrant a 2nd playthrough.

With games like Shin Megami Tensei though, where the main paths might not be clear-cut, I'll pick the path I can relate to more. With SMT, that generally means the Chaos path, since I relate more to characters with that alignment.
