“To arrive at a just estimate of a renowned man’s character one must judge it by the standards of his time, not ours.”
Crap quotes like this is what people use to justify slavery, fascism, genocide, apartheid.
I find it much more compelling to fully see some negative aspect(s) of someone's past existence while accepting that if I grew up in that era, I would have vastly different morals and probably be fine with that.
Judge others not too harshly if you may, since you will also be judged further down the line and most surely will be judged as inadequately moral or good by their standards, didn't do enough to help preventing some proper shit happening/will happen and so on, rather looked away while milking some comfy job for those sweet dollars (we all have kids and families and mortgages and dreams I know, so does everybody else).
Most people here work for FAANGs of this era for example, hardly moral corporations by any metric and some literally sowing evil ie in cancers called social networks and their gamifications or pushing unwanted ads / outright lies into every eyeball they can reach. And those companies are hardly the only black spots on current society, I'd even say purely moral work is rather rare.
