Well, we'd all improve our own lives for the better. It's just I wouldn't dabble too much in others' lives, unless they looked like they really needed it. And I'd likely do a subconscious karma scan to see if they deserved it.
Criminals might not be harmed by me, but they'd certainly be punished wherever I found them.
Though, admittedly, I'm pretty lenient to my enemies at first, and I've always had a soft spot for anti-heroes, so long as their "Chaotic" leans more "Chaotic Good" than "Chaotic Evil".
“…Judge not what a man has done, but judge what he could have done if he was a different bloke altogether. For art thou a leper? And a leper can changeth his spots…” --Rudy Wade, Misfits (Series 4, Episode 8)
