Gale doesn't seem to really want to help others, he gives some "approves" when you do, but he never really talks about it outright. He comes off as someone who seeks [Something] and this lead him down a dangerous path.
He mostly talks about magic and knowledge, and the [Something]. Heck at one point he even suggest stealing (Only to roll that back if you point out it's not cool to steal)
To me he's the "crazy mage" archetype more than anything.
Wyll made a pack with a devil, more or less, and tries to atone for it by doing good. All the same time knowing he only has this power because of his pact.
He also doesn't actually seem to only do his heroics for all the right reasons though.
If you think they are just "run of the mill" then it seems to me you haven't gotten further into their story arch?
