The disgraceful:

The problem is that culture on people is a relatively thin shell under which the bloodthirsty savage still lives. And when the "shell" is broken...
By the way, the same Chikatilo was convicted. He killed half a hundred people while remaining mentally normal. As we are with you.

It is the culture you are talking about that only a few people have, the majority are satisfied with comparative civilization, that is. They are slightly washed and thrown with their fists not all in a row, some successfully do without these excesses.
And with Chikatilo, I think you are consciously overwhelming. Many times it has been written and said that at that time there was a secret rule, according to which such spiders were recognized as convicted, which allowed them to be sentenced to death, in order not to excite excitement in the masses again.
