This is not entirely accurate. There are really only two options:
1. accept it
2. do not accept it
The first option is the healthy choice. The second choice will make you more and more bitter and will eventually destroy "you."
But What if You Can NOT Accept it ?
If you can not accept it, then you at least can accept your non-acceptance of it. Any form of non-acceptance will create pain in you, which "you" in turn, will want to project outwards.
If you can accept it, then you can move on from there.
If you can not accept it, the memory of this "bad" will haunt you until you do accept it.
Our definitions of ourselves are not made as a result of something that happens, but are made before anything happens. Ego simply uses what happens to prove to ourselves that "we are" as we thought we were. In other words, it uses events to prove that we are right. "See I told you so," "I knew she was a wicked person as soon as I saw her" ... etc
Bad in the World
Instead of judging that something is good or bad, simply let it be. Leave such things "in the hands of god" so to speak. Earthquakes, tornadoes, floods, wars; what can you do about them anyway? Send them love. Join with the Spirits and God however you understand them, and send love. That's all you really can do.
Bad in your Face
If something happens we don't like, e.g. our dog gets killed by a drunk driver, we probably won't be able "not to judge." The event will raise lots of emotions in us, of loss, and anger. The mind will want to weave stories about it, embellishing it. The mind will want to tell everyone about it to see if our friends will also agree with us so that they too will confirm to us that we were right ...
Instead of using mind to go into judgement, try putting your attention into the body to feel the pain that is there already. Accept the pain and just stay with it. If you can do this, it will simply diminish. If you go back into "mind" -ie thinking about it, then this activity of "non-acceptance" and will simply create more pain, adding to the pain of the loss.
The only wise thing to do, if you want to reduce pain, is to accept it. Shooting his dog won't bring your's back.
Advice from Jesus
"Pray for your enemies." Great advice from Jesus. If you can't forgive it, spend your waking hours praying for the perpetrator of the crime. Send them love. At least you won't be spending your time cursing him.
