If anything "Using violence to fix the world" would be the better thing to be good at since it protects you from the Monkey Paw to a certain extent.
Exceptions:
a "fixed" world being one devoid of humans
a "fixed" world panning out in the opposite way you imagined (everyone is equally miserable instead of happy for example)
Everyone being equally miserable could be preferable to some people being happy, since it gives everybody equal reasons to work towards improving the situation... Except, of course, the monkey paw would ensure that wouldn't pan out
Monkey Paw: Trump and other corrupt politicians being high up the authority chain made sure more evil politicians didn't get authority.
So you kill those as well. Now trust in democracy is crumbling because for some reason a lot of politicians keep mysteriously dying. "Good" politicians enact laws to protect their lives but those laws are bad as well so now you also have to off the good politicians. I hope you see where this hypothetical is going. The world is not so simple that a few well placed assassinations would fix everything, if that were the case it'd have been done before.
