My games (and characters) vary a lot in regards to ethics/morals. It varies from game to game, but...
I've got a character (human aspected conjurer) who donates a tenth of his profit to charities and to helping the disadvantaged locals due to his beliefs and experiences in the gutter. At the same time, he'll sic a blazing avatar of death on some gangers to help cops in a fight when he could have just left and let them get gunned down, because being known as a guy who doesn't kill cops is definitely a plus, reputation-wise (as in, they're less likely to shoot him in the face first). Two nice acts, two very different motivations.
There's the Infected character (human adept infiltrator) I'm dabbling with right now, a Vampire. He's, surprisingly enough, a very nice guy! Helps people out, avoids hurting innocents, does the right thing for the most part. His method of feeding? He targets the 'wicked', the bad-guys, but most especially he targets Infected hunters and Fear the Dark agents. Both sides of that fight make him want to shove a stake in his own heart. He wants to live in peace eventually, maybe put on a Batman suit once in a while to go get a proper meal. Both sides make that difficult.
Another practically grew up a sniper in the Yucatan (human adept sniper/sneak), and he'll take wetwork jobs any day; that said, he detests collateral damage, tries to get along with anyone he can and will 'hood his services if he agrees with a cause. He doesn't like killing, though he does enjoy the thrill of the hunt, and the satisfaction of success; it's just a job to him, otherwise. It's pretty much all he knows, so he sells his knowledge and skill to make a living.
The next one makes Haze look like a nice guy. Black Magic tradition Mystic Adept, an extremely scary elf Face not because of what he can do, but what he can get others to do. He's amoral and honestly one of the most frightening characters I've made. That said, he puts on a very friendly, helpful face to the world, almost all the time, a good cover to his sociopathy. I used some Criminal Minds episodes as my inspiration.
There's one I played a while back who was a survivor, through and through (elf melee adept). If it didn't benefit him in some way (that didn't have to be immediately tangible or useful), he didn't care. Sure, he did nice things now and again, helped some folks in his neighborhood, that kind of thing; it was all to get them on his side, to get favors, etc. If someone offered to pay him to burn down their homes, he'd ask what was on the table.
My last one is a loving, doting father, a friendly guy who seems like he'd be a good buddy (ork). Put him in a fight and he becomes a brutal, merciless machine, a relentless killer who weighs lives with the bullets he needs to take them. Collateral damage is unprofessional; witnesses are a liability. You have to wonder which side of the fence you'll fall on. He's picking the option that gets him back home to his daughter.
As you can see, it runs the gamut. None of them are saintly, by any stretch, but only one could be described as out-right evil. Even then, he's the least obvious about such information. I do try to match my character's morals to the overall plot, I suppose; the darker the setting, the darker the character.
