How the evil ones try to avoid karmic retribution

The evil ones know they will carry the karmic burden of their actions if they force people to do their dirty work for them, so instead they "encourage" people, through blackmail, bribery and peer pressure, to do it instead. 

For example: if you don't do this thing we want you to do you will lose your livelihood, ability to move freely, social standing, etc. 

So the people still have a choice and therefore carry the karmic burden of the choice they make, even if they would have preferred not to have made it. It's a kind of devil's bargain, which the evil ones have perfected over the years.

That being said, it still won't stop the evil one's from being magnetized to the lower realms of the spirit world upon their death, because evil likes company and their low vibrations will draw them to where they belong.
