Jesus told the man that his sins were forgiven. The religious leaders believed that Jesus did not have the right to forgive people of their sins. :)
The religious leaders were so offended because they recognized that 'no-one can forgive sins except God only.' They thus rightly recognized Jesus' claim to be God in His forgiving the sins of the man, as all sin is ultimately against God, and only God has the right to forgive it.
Because they said only God can forgive sins. They thought Jesus was blaspheming.
The religious leaders once asked Jesus by what power or authority he performed signs and miracles?
Jesus referred to the religious leaders of his time as a "brood of vipers."
In the Bible, they accused Jesus of blasphemy.
They were the Religious leaders of the church
They tried to trick Jesus on a sabath.

The Pharisees which were Jewish religious leaders
Joh 5:18 Therefore the Jews sought all the more to kill Him, because He not only broke the Sabbath, but also said that God was His Father, making Himself equal with God. In this verse we are told why the religious leaders wanted to get rid of Jesus. Jesus healed a crippled man on the sabbath - John 5:6 and when Jesus spoke of God as His Father He was claiming to be equal with God. To the religious leaders this was terrible blasphemy.
They were the pharasees.
When Jesus refers to the religious leaders as a "brood of vipers" in the Bible, he is criticizing them for being deceitful and hypocritical, comparing them to venomous snakes that are dangerous and harmful. Jesus is highlighting their dishonesty and lack of true righteousness.
