I do not consider them bad. They all behave the way I want them to - and it depends on my mood, or on what needs to be done. I choose quest options accordingly to my own preferences.

When I say bad, I mean killing, stealing and picking the 'evil' quest options for better rewards, joining the Dark brotherhood, thieves guild and such.

From this point of view, all my characters are pure evil For example, they all did Dark Brotherhood quests and contracts just to get Shadow Rider passive Any new character will do it too.
They all pickpocket, and steal, and kill if they need loot - and especially when leveling Legerdemain line.
They all choose skill points from Mages Guild last quest

I don't have toons. Never was a big WoW fan.

Regarding character choices, it's situational, usually reflecting what I would do in such an environment.

As there are no real fame/infamy/alignment effects or consequences, it's pretty much RP value only. (This isn't a bad thing, but would be much more intriguing if there were actual in game effect.)
