Steel Wolf, it’s simple to answer.
He was invited to a meeting, so he went to see what it was about. As Perry himself has said, they never invited him back, or to join. So he clearly was not “picked” by those types.

Comforting, I suppose, but I wouldn't trust it an inch towards explaining someone's motivations over the normal human vices.
