Unfortunately it's possible to use drones to do lots of harmful things.  For example they can be used to drop bombs.  And they can be used to attack crowds of people.  And sometimes they can be hijacked by bad actors to harm people, e.g. for ransomware attacks, or DDoS (distributed denial of service) attacks.  They can be used for political surveillance.
