Chris has managed to do something slightly intelligent by deleting this 1 milliwatt act of brilliance, rather than trying to defend the indefensible. Unfortunately, he has of yet failed to delete his confession.
Its no surprise at all that he accepts no guilt for his act, but what is disturbing is his equating the Assistant Manager standing near the exit to some kind of attack.
------
It's the threshold Chris considers violence justified. Inside his workplace, in a company uniform, and making no move whatsoever--Chris considered that as some kind of attack. Just Cause for the pepper spraying.
I grant that talking about this sort of stupidity, after you've done it, is a bad call in general. Even issuing an apology or pleading some kind of psychological state would hurt one's position legally, and so it takes a strange kind of person to want to talk about a Class 6 felony.
Chris hasn't apologized, or even admitted that he'd gone too far with his actions. He has doubled down on what he's done--but even in that tangled web of justifications, he's decided it was self defense. Let's leave out the how Chris' brain came to that conclusion, and ask what it means...
It means that no one is safe around Chris. If for no other reason alone, Chris has got to go behind bars.
