User blog comment:Loudfan21000/Is it just me or can Jerry be just as much as a villain as Tom?/@comment-24200891-20180817060040

In early episodes Jerry was a vermin robbing food and Tom was guarding the food. In realy eps Jerry often attacked Tom unprovoked and suffered no consequences when Tom was punished for crimes he didn't commit. The creators got letters that they feel sorry for Tom, so the creators made Tom a bully, so the viewers would root for Jerry. They went also other route, where Tom was victorious.

One of the worst portplay of Jerry was in episode, where Tom inherited a fortune, but he would lose it if he hurts a mouse. Jerry exploited this rule, so he tormented and bullied Tom, knowing he can't get revenge on him.
