A valid argument is clearly interpretable and either expresses an argument, or a premise or a conclusion that can be used in an argument for the topic of death penalty. An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of death penalty.
PROBLEM: Again I want to reiterate that I am not in favor of an anarchist society where there is no consequences for committing crimes, my point is that society is better served by life imprisonment than the death penalty.

SOLUTION: Valid

PROBLEM: To me, the system's job is one thing: To prevent a similar crime from happening again, not to fulfill a concept that we have invented.

SOLUTION: Valid

PROBLEM: By your definition, the death penalty is hateful, spiteful, etc.

SOLUTION:
Valid
