I am afraid you are incorrect. Intent is very relevant for crimes.
If someone kills someone accidentally, say for example in a car accident they are not guilty of a crime (for example someone jay walking and jumping in front of your car). However, if someone kills someone while drunk driving or say robbing a bank, they are. This is the gray area that exists but basically in the 2 latter situations it would be criminal and the punishment would be penal NOT civil or monetary (though you can have a civil penalty as well). A mens rea (guilty mind) standard is applied which goes to intent.
Furthermore, the implied warranty is uniform commercial code and NOT criminal. There is no penalty of loss of freedom (ie jail) in the UCC and neither should there be.
