Yeah that's not OK.
I get the impression that Linus is in over his head and reacting in a very emotional way. Kinda reminds me of the channel hack a few months ago, both Yvonne and Luke were literally telling him what was going on and what needed to happen, and his tunnel vision just would not allow him to hear them.
That's not an excuse. I think there is/should be a price to be paid. In most things I tend to lean towards rehabilitation with a chance for change, rather than retribution and and destruction. It's a crap situation and I'm disappointed but not surprised.
