There are wolves and there are wolves in sheep's clothing. It is easier to spot the wolves than it is to spot the wolves in sheep's clothing. And, unfortunately, a lot of people claiming to be the good guys are wolves in sheep's clothing. Some of the give aways include the desire to gain and centralize power, and the desire to silence opponents. And we are, unfortunately, seeing a lot of that lately.
People who say all of the right things, and who are on the "correct side" in a battle, are sometimes wolves in sheep's clothing. It's why many initiatives for good ultimately fail. They are corrupted by wolves in sheep's clothing. We have to be aware of that if we want to prevent bad actors from taking control or co-opting our initiatives for good.
