I mean, graded on a wide curve of history right now isn’t complete shit. WW1 saw entire generations of young men slaughtered uselessly at the hands of unelected kings. It was so horrific we actually still try not to use chemical warfare. Absolutely brutal combat with casualties that have hardly been seen since. Absolutely nightmare conditions. We baulk at the deaths of 25,000 over a few months of conflict where WW1 regularly saw those numbers in as little as a day. I do not want to minimize the absolutely brutal conflicts going on now. A newly orphaned child is not comforted by history, but your question seeks context and what else is history for but to contextualize the present?

To me, history shows we have not even begun to experience the the depths of the horror people are capable of. At least in the states decenting voices are not carted away into slavery camps, actively trying to wipe out whole populations with starvation at least has some voices calling out the brutality, I do not see people trying to sell their children to survive like in the depression. These are not far away times where these things happened on a scale they do not now.

Long story short, history has shown the measure of brutality and uncaring to be significantly worse at times. Raw and unquestioned genocide, slavery, persecution, war, child beating, women opressing, and all manner of the lowest acts of evil are the norm of humanity, not the relative peace we have known over the last 80 years. This fact does not make life suck less, but can at least act as a measure for how horrid is has been.
