We would like you to assess the QUALITY of each of the following argument (discussing Death Penalty) and determine if the argument is Valid or Invalid. 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.

My major complaint against the death penalty is that it is quite permanent.
Valid

If you are ready to take somebody elses life, you'd better be prepared to give your life as well.
Valid

You're right about the first part (which only further proves my point), and you're horribly WRONG about the second.

Invalid
