> In American English, the phrase, "He murdered thousands," can't be followed by the word "but..."
Then I hope you've been holding up to the same standard almost every American leader from the latter half of the 20th century till now - whether through political interference, violent regime change to authoritarian leaders, proxy wars, drone strikes or straight up war without a cause.
The truth is that in most people and things, we're inclined to overlook the good for the bad or the bad for the good, depending on our preconceived opinions. Most leaders - especially revolutionary ones - are this, but taken to the extreme, often liberating an entire populace while oppressing another. Which is why they often are notable for both, but more notable for one than the other depending on whether the person you're talking to suffered or prospered under their rule.
We shouldn't be afraid to say in the same breath that a person increased welfare and happiness for some and yet decreased it for others, stood up to imperialism and yet also was the pawn of larger global interests, was persecuted even while he persecuted others, was demonized even while he demonized others, was the target of many assassinations even while he ordered the murder of others, was spread lies and misinformation about even while he spread lies and misinformation about others. All of this happened together.
This doesn't mean it's balanced one way or another, or that one makes up for the other at all. This isn't excusing murder and atrocity - it's giving credence to the complexity of events. It's understanding how the life you live and the limited environment you live it in is very different from the experiences of others, and that people's realities, cares and worries are shaped more by things near them and less by things that don't affect them. It's a way towards understanding why others hold they opinions they do, and also a gateway to criticizing our own leaders and idols in the same way. Leaders should not be deified or demonized, but understood as a whole, wether to understand what to repeat and look up to or understand what never to allow to happen again.
