Exactly, it's as if part of their brain is missing that controls sympathy, so I respond in kind.
I don't believe in anything 'supernatural' mate, as an Atheist, I don't entertain the plausibility of external control of any sort. I do like the idea of it mind, it is entertaining and probably makes for some great film plots over the years.
Things happen where I can say "That served you/them right for being such an idiot", but I don't think of it as Karma as such.
Same as the law of attraction, I think that anybody sitting there, thinking positively in the hope that it will make a difference is deluded, the part that brings you luck and success is the part where you get up and earn it, and anybody who attributes success to the law of attraction is doing themselves a disservice and meriting their own success to something completely non-existent.
