Justification and excuse are different defenses in a criminal case. Both defenses admit that the defendant committed an act proscribed by law. ... The proscribed act is excused if the defendant's violation was not entirely voluntary, such as if they acted under duress or under a false belief.
The difference is that Justification is a social Defense and a Excuse Defense is a mental disorder or something physical wrong with them
Explanation:
Excuse defence is when the defendant admits to committing a criminal act but believes that he or she cannot be held responsible because there was no criminal intent. Excuse defences that are used in courts today are; Age, Mental Disorder, Automatism, Mistake of Fact and Mistake of Law.
Justification is a defense in a criminal case, by which a defendant who committed the crime as defined, claims they did no wrong, because committing the crime advanced some social interest or vindicated a right of such importance that it outweighs the wrongfulness of the crime.
Capital punishment, also known as the death penalty, is the state-sanctioned killing of a person as punishment for a crime. The sentence ordering that someone is punished with the death penalty is called a death sentence, and the act of carrying out such a sentence is known as an execution.
