This farmer sounds like a complete horse's rear end! I'm not saying the "hunters" (people who trespass to hunt are not "hunters" in my book - they are poachers) are justified in being on his land by any means. I also do not know if (and how can this farmer be so 100% certain) that these "hunters" cut his fence.

Sure would be bad if maybe the "hunters" got some bad directions or info and were just honestly kinda lost or misdirected and their pickup gets torched.

Now that we know that the farmer is also an arsonist there are some other things to consider.

Just because someone's vehicle or other property is on your land that does not give you a right to destroy it or hold it's possesion. I know here in IL that is true because I do my best to keep people off my shop's property and even if it's posted - the law is more on their dang side.

The farmer would have looked pretty dang foolish if his little act of arson wound up getting out of control. Fires can get out of control VERY quickly.

"Dang! I got a forest fire on my hands!" (How you gonna keep your forest fire from burning up your neighbor's property?)
