If conservatives are as morally bad as some leftists make them out to be, shouldn't we expect to see an enormous difference between how well conservatives and leftists treat people in their personal lives?

The way some leftists describe the moral deficiency of conservatives, it should be plainly clear when analyzing how conservatives treat people in their personal lives that they are bad. In reality, I don't see it this way. There are certain dark personality types that I've noticed are drawn to conservatism, but I've seen the same thing with leftists. If I met 10 random conservatives and 10 random leftists, I'd probably expect the leftists to be slightly better people on average, but it's not a great difference at all. Whereas, to hear some leftists tell it, it should be this huge difference.
