I got a comment on My Post called: Keywords Steele from Balto. The Comment was the following: Didn't Steele try to kill Balto and would rather let the entire city die from sickness just to stop him? what did Buster do again?. 
My reply to is the following: The reason why Steele tries to kill Balto was this: Steele, too prideful to admit his failure, Balto tries to help but Steele, despite the other dogs, doesn't want him to, he attacks Balto in an effort to kill him. He prevents Balto and the sled team from returning with the medicine, not caring that the children will die if the medicine isn't delivered.  
Steele is highly motivated by fame among both human and animals around Nome, Steele takes pride in his popularity amongst both the village humans and the dogs, often showing off in front of his admirers. In many ways, Steele wants to be the hero. Steele wants to stop Balto because Balto was going to save the town not him.
Steele the Alaskan Malamute always felt almost like an egotistical type of person. Not awful and horrible, Evil-Dog. 
As for Buster from Lady and the tramp 2 he Attempted murder. His Goal was To get revenge on Tramp for choosing Lady over him. 
Buster Personality is like this: Mean, cruel, selfish, deceitful, serious, vain, pompous, unfriendly, cunning, strict, sarcastic, manipulative, backstabbing, unsupportive, arrogant, intelligent, argumentative, quick-tempered, dishonest, treacherous, ruthless, territorial. 
In ways, Buster from Lady and the Tramp 2 is the awful and horrible, Evil-Dog that Steele from the Movie called Balto never was.
