Suffering is not a catch all excuse for behaving like an asshole to your only allies. The Emperor screams eternal upon his throne and weeps for the fate of mankind, he is still a monster. Saying 'he's paranoid so we have to cater to him' is akin to saying 'he's a narcissist we have to kiss his ass', it is a problem he has, not his species, not the Teket, he has to the problem and if we tiptoe around him we would only be enabling him. Would you be Ok with killing Marjak to keep Vlahak because Vlahak will probably be more influential? That does not sound very moral and it may well be the outcome of No.
You missed my argument.
I don't like Vlahak overmuch, but his grievances are not irrational, and we have to work with him if we have to work with the Autonites.
And no, I won't kill Marjak to kill Vlahak. That's not what we're voting for. Stay on topic, and don't use rhetoric to deflect.
