I don't know if a crusade from the surface is the best approach. if its our only approach so be it but even the strongest coldest of people would be affected. the problem with sending in evil or cruel humans is if they arent already sworn to evil then could be turned or chose to turn. maybe we send robots. or flood it. or incinerate. but even examining the aftermath and reporting it openly will affect the population. that is to say if its not after surface level global turmoil. and what sort of mercy do we show to people who have been born and raised in an evil environment. no speech or socialization. blinded in the dark, arms cut off. forced to run around and bite things. i dont think a lot of this is even filmed for entertainment. they just like that it exists.
