Sorry for the two-fer, but I wanted to post a new group to see what people come up with - a less genocidal variation on the current team.
The Climatologist has traveled forward and seen how truly horrific mankind's influence has been on the Earth's climate. Spoiler alert: even after humankind is wiped out, the planet doesn't just bounce back in a few centuries, or even millennia. (To be fair, it was actually mankind's attempts to reverse the damage that actually hyper-accelerated it, turning the Earth into a Venus-like blazing hothouse where no life can exist. Unintended consequences, what can you say?) The only option is to remove humanity from the equation before they *truly* screw things up beyond repair.

New Team: Divine Right
This group of six psychics / oracles / prophets have "seen" the future and feel their technically criminal acts are fully justified based on that future. (Actually, "those" futures, as each has seen various different snapshots of the future upon which they base their criminal actions. For instance, one may have seen the growth of a mass-murdering cult, while another may have seen a company causing widespread environmental damage, a third may have seen a local politician who becomes President and starts World War III, etc.)
Please have members using different types of divination / prophecy. (e.g. psychometry, astrology, tarot cards, runecasting, dream interpretation, palmistry, crystal ball visions, visions from God, etc.) I'd also prefer if their crimes didn't include mass murder, even if they feel that the ends justify the means.
