A bruised reed he will not break, and a smoldering wick he will not snuff out

Matthew 12:1-21
One greater than the temple is here - Jesus.
I desire mercy, not sacrifice. For the Son of Man is Lord of the Sabbath.
This is fulfill what was spoken through the prophet Isaiah. Jesus is the Lord.
“Here is my servant whom I have chosen, the one I love, in whom I delight;
I will put my Spirit on him, and he will proclaim justice to the nations.
19 He will not quarrel or cry out; no one will hear his voice in the streets.
20 A bruised reed he will not break, and a smoldering wick he will not snuff out,
till he has brought justice through to victory.
In his name the nations will put their hope.”
Why?
The antagonism(對抗) runs so deep that Jesus' life is threatened.
The Pharisees see Jesus as the devil's agent, despite the transparent goodness of his work.
Jesus came with mercy and justice, He desire mercy, not sacrifice. It is the spirit of God instead of words or the Laws.
Jesus came to save burdened people in peace but no one will hear his voice in the streets. There is commercial activity and crowd in the streets.
Jesus is the hope to the nations. Jesus is my hope. Jesus is the Messiah as described by prophet Isiah.
How?
Jesus is my hope, who desire mercy, not sacrifice. What I am worry about?
