The phrase "easy victim" implies vulnerability and preyiness, so a few words that could be used instead might be "likely target" or "vulnerable prey". Additionally, "soft target" or "easy mark" could be used in a similar manner. "Gullible" or "naive" could also be used as synonyms to describe someone who is easily taken advantage of. It's important to keep in mind the connotations and implications of the words we use, as they can have a significant impact on how we perceive and treat others.
