This will be hugely destabilizing. Terrible.

Supporting mad murderers in the name of “stability” is just supporting mass murderers.

I never said I support him.

Then what is terrible?

All the people who will suffer and probably die as a result of the instability. Do you think that the world gets better when evil men die?

Likely.

Germany ended just fine after Hitler demise.

But you probably mean very near future.

They actually spent quite a few years (50, give or take a few) snapping back so hard the other direction the government was taking children from non-native Germans and giving them to pedophiles to rape for their whole childhood. So yes Hitler dying was good but instability will most always lead to more suffering.

Edit: Source

So you are arguing that things would be better off if Hitler had won? That’s your actual, sincere argument here? That evil people exist, but killing them results in geopolitical instability so it is terrible when they die?

Fuck that. Kill fascists.
