Planet of Dread by Murray Leinster

_Moran cut apart the yard-long monstrosity with a slash of flame. The thing presumably died, but it continued to writhe senselessly. He turned to see other horrors crawling toward him. Then he knew he was being marooned on a planet of endless terrors._

Moran, naturally, did not mean to help in the carrying out of the plans which would mean his destruction one way or another. The plans were thrashed out very painstakingly, in formal conference on the space-yacht _Nadine_, with Moran present and allowed to take part in the discussion. From the viewpoint of the _Nadine's_ ship's company, it was simply necessary to get rid of Moran. In their predicament he might have come to the same conclusion; but he was not at all enthusiastic about their decision. He would die of it.
