KK on monochrome flop

I know UTG to be a rather loose player who could be on anything from AQ-AJ to 9-10 J or Q.
If an A would have hit I would have folded this flop but as it is I felt there were just too many things he could have had that I was ahead with.
What I want to know is if this push is complete lunacy given my read and the fact one of my kings isn't a spade?
