The word "corruptor" can be replaced by a few different synonyms. One alternative term is "perverter," which suggests someone who causes a deviation from an accepted standard or moral code. Another possible synonym is "taintmaker," which connotes someone who introduces impurity or corruption into a previously pure or unspoiled situation. "Briber" or "graft-taker" may be appropriate if the corruptor is someone who uses money or other incentives to sway others towards their agenda. Finally, "influencer" could be a synonym for a corruptor who has a persuasive or manipulative way of convincing others to act against their better judgment or ethics.
