Climate activism is also being considered an act of terrorism by some now (particularly some Christian party in Germany), dunno if those people label themselves as 'very bad persons'. Probably goes for all terrorists, but this might be easier to relate to as it's grounded in reality and we'd likely agree with the change they seek

Child porn and terrorism are the favorite subjects of politicians looking to enact a new law but idk if it's good to follow that thinking and use it as an example as opposed to a serial killer or something
