I'll only be a murder hobo if I can use a shotgun.
Seriously though, D&D to me was always about gritty, dirty guys doing gritty, dirty things in gritty, dirty places in seach of loot. Look at the illos. in the PHB and DMG fer chrissakes, not a lot of "points of light" glamour shots in there that I recall. Over time, that view has changed a bit, but it's still there in the back of my mind.
