I think he was a deeply unpleasant person who was a very bad ambassador for the sport and made the pro peloton a more unsafe place.
Good riddance.
A lot of the sprinters have been hot tempered but most manage to keep it under control during races. Bouhanni would have benefited greatly from a therapist to learn how to harness his aggression in a productive way. (or teams just refusing to put up with it but as long as he was winning, we know how that goes)
To me striking or provoking another rider during a race or deliberately crashing/aggressively blocking them (and he's not the only one to ever do it) crosses a red line. That's why I hate when teams block the road after a break goes. (I know it's not really dangerous but it's using the bike as an obstacle.)
After the finish I'd love to see more Nascar-style rumbles, of course. That's when Bouhanni's boxing training could have really shown.
