A good thesis statement for an essay on the death penalty might be:
“The Death Penalty is a necessary and appropriate punishment for certain heinous crimes, as it serves as a deterrent to crime and provides a sense of justice and closure to the families of victims. However, the flawed and biased implementation of the death penalty in the United States raises serious concerns about its fairness and effectiveness, and it should be reformed or abolished to ensure that justice is truly served.”
