What did Jesus do to those who crucified him?

Answer 1

If, by "they," the question inquires about what they, Joseph of Arimathaea and Nicodemus, did to Jesus when He died:

"...He [Joseph] came therefore, and took the body of Jesus. And there came also Nicodemus, which at the first came to Jesus by night, and brought a mixture of myrrh and aloes, about an hundred weight. Then took they the body of Jesus, and wound it in linen clothes with the spices, as the manner of the Jews is to bury. Now in the place where He was crucified there was a garden; and in the garden a new sepulchre, wherein was never man yet laid. There laid they Jesus therefore because of the Jews' preparation day; for the sepulchre was nigh at hand." (John 19:38-42)

That's what they did to Jesus.

Answer 2

He forgave them. See Luke 23:32-34: - 'Two other men, both criminals, were also led out with him to be executed. When they came to the place called the Skull, there they crucified him, along with the criminals-one on his right, the other on his left. Jesus said, "Father, forgive them, for they do not know what they are doing."And they [the soldiers] divided up his clothes by casting lots.'
