all in preflop with KK27 in budapest. bad?

This is in a live 2.5/5 PL omaha game in budapest last night. Im sitting in the big blind with kk27, 4 or 5 players limp, one guy raises it to $50 (he did this ALL the time) got one caller and I pushed in the big blind for about $300. I got two callers.
Basically, I just wanted to stuff my hand in with the best of it...I was hoping only I could get the maniac heads up. He actually has some kind of personal vendeta against me hed call me with ANYTHING.

So is this ok, is that trash hand good enough to do this with?
