Do you know of anyone who has used Karma to justify becoming judge, jury, and executioner?

To me karma is a guide for one’s own actions. It is not a guide to judge others, misjudge others, or wish ill will upon others. Wishing bad things to happen to another person is just asking for bad karma. Or am I totally of the mark?
I am speaking of karma in the sense of the present life/ present life cause and effect, not the traditional past live/ next life sense.
