I truly believed (obviously incorrectly) that there was a possibility that Kevin wasn't scum. The evidence that we had on him had other legit explanations (or at least raised enough questions to cause some level of doubt) and I didn't want to discount those possibilities right off the bat just because others did. I could have easily blended in and voted for Kevin during the initial bandwagon on him and no one would have blamed me at the time. Instead, I chose to keep my mind open and consider everything. That wasn't the path of least resistance for a scum. With 4 people already voting for Kevin that day, the likelihood of enough people unvoting for him to save him wasn't great. If I was scum, I stood to gain nothing by openly discussing other alternatives at the time because as soon as Kevin got lynched the spotlight would almost immediately be on me. Additionally, if Kevin actually had an ability that allowed him to survive a lynch, I might have known that as a fellow scum and it would have benefitted me even more to vote for Kevin since he wasn't actually going to get lynched and I could point to it in the future and say "see I voted for Kevin a now known scum."
No one knows who is scum that is given. But we move forward by past experiences. And when Kevin didn't die the first it definitely reminded us that brewers once used this power before in his games. So we jumped on Kevin again. That power was the tell and you really had to be forced into voting for him thats why I'm gunning for you now.
