Given that this was an ethics course, I think it's interesting/surprising that the professor doesn't seem to be trying to engage with what I'm guessing was the course material in this discussion. "Am I the unethical one" the right question? How about "Under which formulations of normative ethics is my behavior wrong?"
1. Is it _good_ to catch cheating? If these are students who are just checking some distributional requirement box, does it matter if they actually understood the material? Potentially there is harm (delayed graduation, literal costs, etc) from failing students (or having them be subject to some other discipline). Perhaps under a consequentialist framing, catching cheaters isn't good. But does the professor have a deontological obligation to catch cheating, and to make a good-faith effort to have fair outcomes in which students who studied and understood the material receive better grades than cheaters?
2. Is the method of catching cheaters relevant? If catching cheaters is good for consequentialist reasons, isn't any effective means of catching cheaters (which does not cause other harms) also good? Certainly the objection that the professor was dishonest by uploading the bad test sounds like it's from a deontological / rules-oriented view.
