I don't have any problem with deciding to blast Faulk there since he's waltzing into a prime scoring area and you want to let guys know that there might be a cost to going to that prime scoring era; however, you've got to make sure you get his shoulder or else you can't make that hit from the side anymore.
"Predatory" is in the eye of the beholder, I guess. I mean, predators in the wild take advantage of unsuspecting prey but, like, that's the best time to hit someone in hockey and it is perfectly fine if it is a clean hit: clean hits can be "predatory" if the definition is something along the lines of "defenseless player" or "unsuspecting". This hit wasn't predatory in the sense that he was hunting Faulk all shift/game or what have you: it is a bang-bang play that would be totally fine if Kadri knew how to hit properly.
But the last part is the rub: Kadri is not good at hitting whereas Wilson is actually a good hitter. Kadri's last two "full" seasons were 2018 and 2019 when he played 80 and 73 games, respectively. His hit totals were only 94 and 85 for those two seasons. He only had 23 total hits in 15 playoff games last season and his final stat line for the first round--and maybe more--will be two hits in two games.
Wilson is basically over 200 hits every season. He's got 15 in three playoff games this year.
I'm not saying Wilson is an angel but, really, the idea that he is the dirtiest player in the league needs to be examined when you've got a guy in Kadri with a long list of suspensions himself, doesn't hit that much and has multiple stick infractions included in that list of suspensions. At least Wilson will fight anybody as well.
