This is true. It is the point of krakoa actually. I would argue that these villains have toned down their rhetoric quite a bit from their past selves in order to maintain the status quo which is krakoa. Can you imagine someone like sinister adopting the “kill no human” law without krakoa? Krakoa has been a melting pot of varying philosophies of mutantdom. It is still in its early stages in regards to a culture. There are plenty of idealogical differences just on the quiet council alone. It makes sense.
