9. The Utter Lack Of Trust
Right from the off we're introduced to Trevor as a total monster of a human being, and for me although that opening action (seen later in this list) put me on a path towards disliking the guy that I would never come back from, due to his scattershot mentality and refusal to stick to any main thought-process made me think he was about to kill off members of the cast at any moment. We do see that Trevor has gotten a Michael tattoo since his passing, and throughout the game there are a handful of scenes where the importance of friends is shown to be one of the only things he truly cares about. However even that is somewhat thrown under the bus due to another entry on this list, leading me to regard Trevor as a complete loose cannon, not trustable to deal with any scenario rationally, regardless of Rockstar's attempts to give him occasional socio-philosophical dialogue as a point of empathy.
