An idea I idly thought about is that of a "Benevolent Terrorist"[0]: one who does great harm to some number of people so that they may make it to a better world. Not entirely original, I suppose, since the Kwisatz Haderach from Dune is the trope definer. But a fun thought I had was what if you ran a ransomware company that just didn't pay? You'd screw a lot of people over but eventually you'd make ransomware a non-business the better you impersonated them and failed to deliver after taking the ransom.
What could go wrong? ;)
