"You shouldn’t talk about sin because Jesus didn’t condemn anybody. He was always loving and kind."

Jesus did indeed condemn some people for their sin. In Matthew 23 He called the religious leaders "hypocrites" seven times. He told them that they were "blind fools," children of hell, full of hypocrisy and sin. He climaxed His sermon by saying, "You serpents, you generation of vipers, how shall you escape the damnation of hell?" (v. 33). He then warned that He would say to the wicked, "Depart from Me, you cursed, into everlasting fire, prepared for the devil and his angels" (Matthew 25:41).
