Why did James Earl Ray Martin killed Luther King Jr?

James Earl Ray disagreed with what Martin was trying to do. James E. Ray was a racist, he hated black people, and he thought he could get paid a lot of money from white extremists for killing Dr. Martin Luther King Jr. He also thought he would be seen as a hero because he shot "The" one who was making all the trouble about Civil Rights. He expected the Klan to see him a hero, thus the reason for his quick confession. He received no money, he only got life imprisonment without parole and died in jail from natural causes. He died at Brushy MTN State Prison in Upper-East Tennessee.
