Bill Chompski,
Khaiden cares about power and fulfilling his desires. Magic is just a tool to that end.
He'll embrace Akras' advanced technology since it offers great power.

He hasn't used Entropic in game yet, since he hasn't needed to. He has used Soul a lot, which let him get back to functional health after getting seriously injured.
