"Preying upon others" often implies a negative and predatory behavior. It can create the image of someone who preys on the vulnerable or takes advantage of others for their own gain. Some synonyms that might better convey the idea of exploitation or manipulation include "exploiting," "manipulating," "coercing," "taking advantage of," or "using." Alternatives such as "bullying," "intimidating," or "preying on the weak" might convey a harsher or more aggressive tone. It is essential to choose the right words when talking about negative behaviors, so people can understand the severity of the situation.
