See this video from 4:20 forward to see Martin Sheen’s reaction and Charlie’s reaction to his dad’s judgement.

In Sheen’s reaction shots you can see his nostrils are clearly messed up.
I don’t care what the Dad’s politics are - this is just devastating for him to watch his son go down this path.
I don’t see how this can turn around from soon to be death without someone institutionalizing Charlie.
