Rainsford does not believe animals and people are the same. Here he claims that he is a hunter and that if General Zaroff hunts people, he is a murderer. This implies that Rainsford does not feel as if killing animals matters or that they feel anything at all the way humans do. He believes that a kill for sport can only be considered murder if it is a human being killed.
Earlier on in the short story, he also mentions directly to Whitney that he believes animals feel differently than humans do, and that their lives do not matter in the way his and Whitney's do.
Punctuation marks are important for recognizing the end of a statement and or drawing some out with an ellipsis. If you do not put them at the end of your writing/sentence, unless using a question mark(?) or exclamation point(!), then the reader/grader will not be able to know where your sentence ends and the new one begins, therefor rendering it a run on sentence.
