"They shall be ashamed and dismayed." The sages say that in the future, God will take the righteous and show them Gehenna (Hell) and the empty places within it, and say to them, "These places are empty for you. You have merited them by doing good deeds, and you will inherit Gan Eden (Paradise)." Similarly, the wicked will be taken and shown Gan Eden with empty places within it, and God will say to them, "These places are empty for you and your friends, but you have obligated yourselves with evil deeds, and you will inherit Gehenna."
Rabbi Yehoshua ben Levi said that God does not curse the wicked except with shame. Furthermore, He multiplies their curse, as it is written, "They shall be ashamed and dismayed exceedingly." And when God blesses the righteous, He multiplies their blessings, as it says "No shame, no humiliation, ever again for those who keep my commands" (Isaiah 45:17), and "You shall eat abundantly and be satisfied, and you shall praise the name of the Lord your God, who has dealt wondrously with you" (Joel 2:26).
