Zhen, +1! Here's my humble contribution: The nature of evil is to seek application. In various forms, it penetrates the souls of people to realize itself. And not every person has the strength to renounce it. Many become accustomed to malice and generate new evil, even more insidious and destructive. However, not everything is hopeless. Good is also capable of multiplying, if someone sows good seeds. But let's not look around – mercenary work is unacceptable here. And let's not put it off until later – life has only one spring.
