Two things can both be wrong
When one of those two things is fascism, the other one is irrelevant.
The difference in magnitude between how wrong one objectively is and the other might be is so cosmically vast, that any comparison is moot.
You either stop fascism, by any means necessary, or you (and everyone else) suffers the consequences.
Again, there is no possible middle ground.
There is no possible “yes, but...”.
There are no other priorities.
There's no possible bargaining, rationalisation, justification, or argument.
Any attempt at such is either irrational or malicious, or most probably both.
When faced with an existential threat, you either do everything in your power to stop it, or you suffer its consequences, and allow everyone else to suffer them.
If you are not actively opposing fascism, you are enabling it.
You are a necessary accomplice and collaborator.
You are effectively indistinguishable from any other fascist, and equally responsible for any harm they cause.
Accept your responsibility and, if you don't like it, stop trying to justify yourself and start doing something about it.
It was the black death.
It caused wages to rise due to the reduction in available labour force, and increased social mobility (through the amount of positions it left available) and personal wealth of the survivors (through inheritance and looting), kick-starting the renaissance.
From there, it was all dominoes. More wealth allowed more commerce and innovation (here's where the naval technology comes in), which led to the discovery and ransacking (and eventual colonisation of America) which led to more wealth and commerce and innovation and social mobility, which led to less social stability, wars, more innovation, a series of political, social, and industrial revolutions, a vicious circle of runaway capitalism devouring everything in its path, the ideal of eternal growth, and the raping to death of the only world we have.
No black death, we'd probably still be living in the middle ages (with better plows and bigger cathedrals, sure, there was still plenty of innovation back then), and complaining about the cold instead of the ever rising heat.
