Should you use the death plenty?

This is a highly debated topic nowadays and has been for a while. Is the death penalty too harsh? Is the death penalty the right punishment? In some cases, say a serial murderer, the death penalty is justified because they took or ruined multiple lives and is especially applicable if they feel no remorse. Honestly, there isn't exactly a right or wrong answer to the question of using the death penalty. Situations vary and people's minds also change.
