No, do not say that these people are sick. Schizophrenic people are sick. Bipolar disorder patients are sick. People who suffer from major depressive disorder are sick. Saying that someone who does and says what is clearly evil simply absolves them of responsibility, as if they had some organic malfunction in brain circuitry beyond their control.
This is different. This is wicked. This is a willful abandonment of themselves to the indecent, the foul, the ugly. This is evil. Most of us do some small evil from time to time, but these people choose to live this way, and think themselves good, and refuse to seek the Light. It is a decision for which they are entirely responsible. Don’t absolve them by saying they are sick.
I meant sick as in disgusting not ill.
You have a very good point!
