One characteristic that might indicate someone is a sexual abuser is:

A history of testing boundaries can be a significant indicator of potential abusive behavior, particularly in a sexual context. Individuals who frequently push limits may demonstrate a disregard for consent and an inability to respect personal boundaries, which are crucial elements in healthy relationships. This characteristic aligns with patterns often observed in those who may engage in manipulative or coercive behaviors.

In contrast, experience in physical fitness, active community engagements, and working closely with rehabilitation programs do not inherently suggest abusive tendencies. Physical fitness can reflect a variety of healthy lifestyles, while community involvement and engagement in rehabilitation programs typically indicate a commitment to positive societal contributions and personal development. These traits are less likely to correlate with abusive behavior and instead support pro-social behavior and responsibility.
