The real religion?

[brewer]

bold mine

You're kidding right? Or just cherry picking again.

Matthew 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill. (just said OT counts)
Matthew 10:21 And the brother shall deliver up the brother to death, and the father the child: and the children shall rise up against their parents, and cause them to be put to death.
Mark 7:10 For Moses said, Honor your father and your mother; and, Whoever curses father or mother, let him die the death:
Luke 12:5 But I will forewarn you whom you shall fear: Fear him, who after he has killed has power to cast into hell; yea, I say unto you, Fear him.
Luke 12:47 And that servant, who knew his lord's will, and prepared not himself, neither did according to his will, shall be beaten with many stripes.
Acts 12:23 And immediately the angel of the Lord smote him, because he gave not God the glory: and he was eaten of worms, and gave up the ghost.

There are more.

First, we were very specifically talking about positive and negative changes in the life of a person. You have listed out of context verses that don't have any bearing on the subject. From your post...

...And I notice you only discuss positive changes, no negative, that's not very honest.

They have bearing. You asked "What negatives are there in NT Christianity?" This is what is in the NT. They are negative. To pick only the nicey verses is, let's see, maybe in your terms, to bear false witness.
