Matthew 5:21 Ye have heard that it was said of them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:
This breaking a "law of Moses" putting you in danger of judgment.
Matthew 5:22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
Is Jesus saying that "thinking" or "feeling" now puts you in danger of judgment? That doesn't seem to be less intense, this seems to be a more intense judgment
