it like asking if you'd act better if you seriously believed in Kharma...

of course!...I'd stop and think and analyze and meditate and plan and all that even more than I do now. Come to think of it, I'd barely have time to act, which would make life calmer, though less productive, perhaps.

I like to think that I follow a version of the "Golden Rule" and have a reasonably altruistic attitude...but that scenario would test me, for sure.
