The crowd was mostly influenced by the chief priest and teachers of the laws, the Jews. They were feeling inferior and threathened when Jesus began to gain popularity. Jesus's teaching is putting the authority of the chief priests, teachers of the law and the elders at stake.

They were unhappy because Jesus prolaimed as the Son of God. To them Jesus was blaspheming. This has put their beliefs all these while to be wrong.

Therefore, they wanted Jesus to be crucified realising the popularity He might gain if He is t continue his preaching.
