Question: I've always wondered if Booth shot those hunters because he was pissed off at that one guy for shooting the duck; or because he felt it was the perfect time to test the effectiveness of his home made gun. Any thoughts on this?

Chosen answer: The two hunters had now seen his face so they had to be killed. If they reported Booth to the police as "a weirdo in the woods with a powerful gun" (or whatever) his face would become known to the authorities and his chances of getting anywhere near the president would be zero.
