Ja Rule Karma ?

I was just thinking today, about the whole situation, sabotaging & destruction of Ja Rule's whole career since the coming of 50 cent, & I wondered if it was karmatic how this had happened being Ja Rule had allegedly stole DMX's style from him some years before he blew up with murder INC & they officially went to the top.
And is whats happening to 50's career now the karma from that(his actions against JA) ?
