Jack's reasons for not going to war reflect the POSTCONVENTIONAL stage of moral reasoning established by Kohlberg.

Explanation:

Postconventional

This is the stage in which a person start to establish and follow their own moral principles, focused on abstract principles and values. A person start to realise that not all laws are fair and they believe such laws shall be removed. In this level a person start to exist as individuals away from the whole society in such that they will gladly go against principles which do not align with their principles even if it means not abiding by the law.

A person believes and stand strongly in their ethical principles such as a right to life.

Jack is willing to go to jail rather than taking part in armed conflict because he believes in every human right to life hence he would rather stand by his ethical principle even if it suffering harsh punishment.
