This chapter explores the potential risks and benefits associated with defending peers in bullying situations. While defending is generally considered prosocial and linked to positive traits, it can also involve personal costs, such as social retaliation or becoming a target. On the other hand, defending may enhance peer status or foster stronger social connections. The chapter emphasizes that defending is a multidimensional construct encompassing direct intervention, emotional support, adult involvement, and indirect strategies such as distraction. The diversity of strategies reflects the varying risk-benefit profiles of different actions. It also notes that some youth, such as those with a history of victimization, may face heightened risks when defending others. The chapter encourages a balanced view of promoting intervention and consideration of both the protective and potentially harmful consequences for the defender.
