Violence only leads to more violence, and this cycle of killing will never bring true peace

While ISIS has committed terrible acts, celebrating someone's death—no matter who they are—feels wrong to me. We should be focusing on addressing the root causes of extremism, not just eliminating individuals. Every time a leader is killed, another one rises in their place, so is this really solving anything? I wish the world would invest more in diplomacy, education, and economic opportunities instead of relying on military force.
