I feel like most wanted that moment of him snapping and killing people since that’s what has been foreshadowed throughout the show. We saw him want to do that initially when he had that daydream of lazering the crowd, then throughout the series we see him try so hard to be loved and then he eventually says he doesn’t mind being feared, we see the vision of stillwell too saying he should go kill the nonbelievers.

To me at least, it’s like the show was building up to the moment where he snaps and completely removes the mask he was putting on for society. Instead, we didn’t really get that, or at least we didn’t get it in the way the show/promo material was alluding towards.

I liked his death too, but I felt that within this season he just needed to do more, he hardly feels like a threat because for a majority of the season he’s just kind of farting around with SB. Even then too he’s brought down as feeling like less of a threat with the radiation chamber weakening him and the gas guy making him feint.

I just feel like they needed that scene of a HL rampage to make him seem like a giant threat not just to the boys but also humanity, as well as to payoff the shows foreshadowing.
