compassion towards evil

Let me write something lingering in my head these days.

I have nothing to do with this but when I read news this week, I felt that the world is rotating in reverse direction. Because People were condemning Arnold Schwarzenegger for refusing to block the execution of Stanley Tookie Williams.

That Stanley Tookie Williams killed four people in 1978. And since he is the founder of a gang which committed countless brutal killings, he is such a dangerous evil. 

For example, look at this:

Williams allegedly said about one of the killings, "You should have heard the way he sounded when I shot him." According to the governor's account, Williams then made a growling noise and laughed for five to six minutes.[link ]

What a dangerous evil he is!!!! He was having appetite from killing. Such an evil. Such a killer. 

I believe Arnold Schwarzenegger made right decision by not granting clemency.

But people are protesting Schwarzenegger. European countries condemned a lot. What the hell is happening? Is this compassion towards evil????? I want to ask those people who protest like this… “Will you say/do this if the people who were killed are your family member??? Answer me correctly, genuinely.”
