When someone is promoting lies, hypocrisy, contradications and various mind control techniques, they are not bad, not evil, and do not need punishment, revenge or hate. They are simply sick, out of balance, confused and attached to false beliefs.
There are times when such persons need to be stopped before they do yet more harm. And they will gladly exploit persons like you who refuse to judge according to good or bad.
They can only be stopped by using resources of the law which does judge according to good or bad.
Many of these persons are insatiable, care nothing for conventional moral standards and will only be stopped by imposition of force - arrest and detention.
They teach us to fear judging according to good or bad because they know
our hesitation gives them greater latitude to pillage and plunder trustful hearts.
For examples, read about Rajneesh (his followers poisoned a salad bar in an attempt to get local residents sick and sway results of an upcoming election), the NXIVM group, which has been stopped only because its leader and his senior followers have been jailed, and the Japanese Aum sect, which used lethal poison gas to attack subway passengers.
