One bizarre refereeing decision doesn't make the player an idiot - wait to see if brain explosions are a trend.
at minimum a player committing two fouls in the space of three seconds indicates a temperament issue (his second foul wasn't 'strategic')
Its a one off instance and I can almost guarantee he'll never make that mistake again, personally not willing to read anything into it, beyond the fact that someone should have a word to the ref about not ruining football matches for sharks and gigs.
I've seen many, many football players make challenges like that second one and most of them don't have temperament issues. Far too small a sample size to make any calls like that.
