It's possible for a crime system to appeal to most people. A toggle for someone to disable different crimes and for lots to replace stolen items could limit opening people's trauma and minimalize annoyance. In TS3, sims that had been caught committing crime were taken to jail for a bit. That was an acceptable consequence because it added realism but wasn't long enough to be truly obnoxious. Combine crime with the current reputation and sentiments systems and we have a pretty good base for consequences.
Like others have mentioned, random crimes according to professions would be cool. A klepto sim.. honestly wouldn't change much, but a mean or hot-headed sim could commit vandalism. An evil sim could commit any crime, but would be more prone to super crimes.
Speaking of super crimes... this would go great in a superpowers/natural disaster/crime pack. Those of us who love that danger factor NEED this pack so badly. Just imagine a boring night at the bar and suddenly a weirdo in a costume summons a swarm of bees or starts freezing people and taking their simoleons. Then cops or a superhero show up, and a showdown happens. Meanwhile your sim is trying to chat up the cute bartender who pees themself with fear and then dies from embarrassment. Your sim gets hit by a stray lightning bolt and passes out in a cloud of bees.The grim reaper swing by to reap the barkeeper and just eats a rotten bowl of olives. The chaos potential is limitless!
