Are cartoons violent?

Nowadays, we´re living into a society full of information. This can be good or bad . However, The Children´s education is very important and I think that not always the T.V give them a good example.

If we watch the T.V everyday, the majority of the programs are too bad because show us other point of view about the actual life. T.V shows a life full of material things and It doesn´t show the real situation with diary problems and how this problems can resolve with the moral and friendly values.

Cartoons are significant in the children´s life, they learn to act following the values which are showed in T.V.
What is your opinion abut this?
