Why are they all acting weird about Victor?

Why are they so angry at Victor? Why isn't he allowed to vote for Arisa? He has no loyalty to her, it's not throwing her under th ebus to be like 'yeah, you randomly taking my hands was weird.' He even said at the time, 'you're not killing me are you?' Why is he the only person who's being called out for voting for who he wants to vote for? This is so weird.

I feel like people don't like that he got a shield instantly so they've just decided he's the one to hate now.
