No, the teen rating fits perfectly. I've seen people request what rated M things they want in the game (saw someone say domestic abuse and r*pe for some disturbing reason) and I don't want those things touching my game and I genuinely don't understand why anyone would want that in their game.
There are a lot of darker things that can be incorporated in a T rating without it becoming inappropriate for actual teenagers. Instead of bloody massacres, they could have Sims poison others through food or drink and there could be murder that way, or have Sims that are arsonists set a house on fire, etc. I dont think the Sims should ever mimic reality completely, I don't play it to experience the same horrible things that already plague the world.
