If a person say for example violently assaults you (an exterior action) doesn't that reveal that there is something wrong with that person on the inside (interiorly).
Also doesn't justice and the protection of the good people in society require that men who do wicked things be restrained from doing harm by the threat of punishment by a legitimate authority (ie. the lawful government (give to caesar)). It would be wrong to treat a mass murderer the same as someone who feeds the hungry surely?
And God also is Just so won't he punish a person for doing evil?
Also from scripture I cannot find what you say about Jesus telling us to treat everyone the same, he seems to say the opposite in certain passages for example:
" 15 But if thy brother sinneth against thee, go thou, and reprove him, betwixt thee and him alone; if he heareth thee, thou hast won thy brother. 16 And if he heareth thee not, take with thee one or twain, that every word stand in the mouth of twain or three witnesses. [Truly if he shall not hear thee, take with thee one or two, that every word stand in the mouth of two or three witnesses.]
17 And if he heareth not them, say thou to the church. But if he heareth not the church, be he as an heathen and a publican to thee."
Matthew 18:15-17
