The penalty phase in the trial of convicted Boston Marathon bomber Dzhokhar Tsarnaev begins Tuesday.

The same jury that found Tsarnaev guilty on all 30 counts against him last week will determine whether he will be sentenced to death or spend the rest of his life in prison.

Northeastern University Professor Emeritus Edith Flynn argues that the death penalty should be off the table.

“If this guy gets the death penalty we’re gonna be hearing more than we ever wanted to hear about Dzhokhar Tsarnaev [...] we are playing into the hands of the terrorists," she said.

Dr. Zuhdi Jasser appeared on "Fox and Friends" to discuss if giving Tsarnaev the death penalty would actually be giving him what he wants by making him a martyr.

Jasser asserted that the death penalty should be the correct punishment, as the American justice system should not be adjusted because of terrorists' theology.

"We need Muslims and imams to stand up and say, 'This guy deserves the death penalty, so he can get 72 Satans and go right to hell,'" Jasser said.

Jasser pointed out that former Al Qaeda leader Anwar al-Awlaki hasn't become a martyr after his death in 2011, nor has Ft. Hood attacker Nidal Hasan, who is currently on death row.

"If we're going to win this battle of ideas, we have to show them that American justice is black and white."
