Is Jesus really fufilling the laws or changing the way they are set up?

In Matthew 5-7 Jesus is fulfilling the laws. When you really read what he is saying, you begin to see that the laws are almost becoming more strict. Instead of adultery just being when you have relations while married, it is just simply looking at another woman. He says that it is no longer an eye for an eye, but if someone strikes one cheek you must turn to the other side. When he is talking about doing good works, it is not only doing good works but doing them in secret. Jesus says"do not let your left hand know what your right hand is doing so that only your father in heaven may know." Basically everything the people thought was right was changed. Because Jesus was fufilling the law, they were made stricter and had more rules to them My favorite part of these verses is when he says to be the salt and the light and that we are a city on a hill and we must shine our light for all to see. It is just so powerful that Jesus is declaring this to a crowd of people, it is not in a parable but just straight up go shine your light which to me is awesome.
