Samuel is a Yandere. Not just any Yandere. One who's obsessed with two girls, of which are Ashley and Rain. You may think that maybe he's less evil than Gerry. And I'd say he's less psychotic. But particularly he's almost as much of a jerk as Alexander. Just, in a slightly different way. He hates half of the people he knows and sometimes bullies people. And of course he also kills people. He's a Yandere after all. Samuel is often said to be "The mean kid" which is somewhat accurate. That's basically who Samuel is.
