The t.v. shows don't show it because it was made for kid audience (loved Sonic X series) The original Comics was dark and depressing it doesn't sugar coat anything, it's fully of death and destructions. Eggman actually killing a lot of people, there is even a scene with I think sonic, sitting in a graveyard looking at the grave of someone close to him who died earlier in the comics and he is extremely depressed at the time and I don't mean sad depressed I mean suicidal depressed... it is a lot darker than originally thought.
