PLEASEEE HELPPPPAfter, putting myself in Heniz shoes I would probably do the same as him. This is because even though breaking in and stealing is illegal you have to look at why he is doing this. He is breaking in and stealing to save his wife, to me saving a life would be worth committing a crime. Also, the crime being committed isn't the worst crime you could do. However, I would try a bit harder to raise the money. For example, nowadays there are many other ways to raise money such like go fund me etc. that I would use to try and raise the rest of the money, before I commit a crime. Is this statement proconventional, conventional, or post conventional morality?
