@nachtness Even if people had later accused him, he would have had the plausible deniability on his side. He could just say he slew some criminal arsonist who was sneaking around in the darkness, trying to spread the fire. How on Earth was the supposed to know the shady lowlife was in fact a neighbouring lord?
But yeah, not this MC. He wouldn't settle for the simple way. Who knows, maybe this way he will get more compensation from the culprit. Unless the author forgets all about it. I mean, it was just a single village burned to the ground, nothing much, I'm sure.
