Well, the bolded part spells intolerance as opposed to Sydor's tolerance billy but you already knew that. It is possible something family linked led up to this but fact is, if he was still able to drive, altough poorly, he must have had started drinking again before this sad incident given he should have fell asleep or crashed right away.
Guy needs help, will probably lose his job, maybe his wife/kids.
Sydor is sick, not a bad guy like Kane, just sick to the bones.
Inexcusable? Depends on if you think he should get a last chance.
This said i will never condone such a behaviour, in hockey, if there's a victim, the price to pay is much higher accordingly to the injury.
There was no one harmed but there sure was potential though!
I bet his life gets destroyed while a-hole Kane gets away with actual consequence (alleged).
I wish Sydor the best considering...
But yeah, he'll get it & should, if only as a public message.
