Why do Jews use sesame oil after death?

Jews use ointment after death because it symbolizes the suffering on the eve of Jesus' crucifixion. According to the Bible, when Jesus was crucified, his body suffered serious injuries and sufferings, and the ointment represented these pains and sufferings. Applying ointment is a way to commemorate the crucifixion of Jesus, and it is also a way to express admiration and reverence for Jesus.
