You just called it a standard I didn't.. Your statement that this is a standard is illogical. His own motivation in fact is just that- His. In my mind it points strongly to HIS culpability...

It is anything but illogical. If I remember my college logic class, here is how I would map your argument.

(A)A person cheats on their spouse.
(B)The person's spouse turns up dead.
(C)Therefore that person must have killed her.

A + B does not necessarily = C

And I don't see what is illogical about a statement that says cheating on one's spouse is not an uncommon occurance and that everyone that cheats on their spouse should not automatically be assumed to be a murderer.

The problem I have is that you termed it a standard(as a custom, as a norm) spouses who cheat as a custom commit murder. I did not imply that custom as a standard. You did.. it's certainly false. If you implied that "all" married persons who cheat murder than that is illogical

Obviously, normally people who want to be free of their spouses customarily get divorced. However, that is not always the case. I think Scott's own motivations are just that "not" the norm. That's why he's on trial for his life..
