Nekomon, namaste ....
If you take another look at the Reiki principals, you will see that Reiki comprises a compassionate way of being.
Sometimes, when we "judge" other people, what we dislike in them is what actually, we dislike about ourselves.
If we find ourselves in an experience we are not happy with, there is usually some learning experience that we need to take from it.
Love and light,
