I don’t think that a religious person who accomplished so much would shy away from killing themselves and everyone else, they will even have some religious justification for it. There are also groups out there who advocate for forcing gods hand into starting the judgment day already. The religious zealots are not the only risk, there are quite many nihilists out there who don’t believe or even care about their impact on the world.
