Whatever you think, pessimism will make for a sad life because if you always expect to be disappointed then you forever will be disappointed. I have seen many people change their mind on roles over the years, and while there is toxicity the number one thing that causes a group to crumble is lack of communication regardless of the group of people. Talk to people even if they are random because you cannot assume everyone is always in the same frame of mind as you are at any given time.
