In 2015, Billingsley was sentenced to 30 years in prison, with 16 years suspended, after he pleaded guilty to a first-degree sex offense, court records show.

Simply put, there exist a non-trivial amount of people who were wrongfully imprisoned and later freed that would be dead now if we were looser with the death penalty. Some righteous bloodlust is not more valuable than their lives.
More simply, if you were wrongfully imprisoned, you’d probably be quite thankful for how hard it is to actually apply the death penalty. It’s really that simple.
