Even if your bar for being "decent" and "empathetic" means not murdering, raping, or regularly doing other horrible physical or psychological things to another person (which is an incredibly low bar) these percentiles aren't even remotely accurate.

What you really mean is 99% of people treat the people close to them with the bare minimum of decency and empathy and don't actively harm them. Even that probably isn't true. Also that is in a place where being decent is easy.

If you want to know what people are like by default just remember, in Rwanda the Hutus killed 800,000 Tutsis with machetes in 100 days, probably hundreds of thousands of people participated in genocide directly because some men on the radio told them to. That was 30 years ago. Or remember everyone in Germany played stupid when the Russians and Americans found the camps, they all knew. That was only like 80 years ago.
