It's impossible to know which hit or action is career ending and I don't think that has happened since the Hossa hit. Do I want something to happen to McDavid where he will be in a wheel chair for the rest of his life? No. Would I be against the knee torpedo Brown did to Hertl against a scum bag like McDavid, absolutely not. I am cool with others hating Brown and wishing shit on him because his hits like even the one of Hertl weren't accidental. If Fiala goes around injuring players like McDavid then I would be understanding if he got Anderson'd.
Im not talking about a permanent injury like Bertuzzi, I am talking about a cast for a couple of months is a nice reminder to not be a dirty piece of shit.
If you want me to clarify anymore where I stand, I would be completely fine with the run McDavid did on Anderson happening to him every time he was being a dirty piece of shit. Get a penalty and slightly injure the dude? The league didn't seem to think it was a big deal when Anderson got caved in like that? Why not McDavid?
