Just because she has been killed does not mean that one can reap superlative praises on her!
Benazir had already been the Pakistani PM twice before and her performance then was nothing more than ordinary. She was just like any other civilian Pakistani leader who towed the favourite anti India line to stay in the good books of Pak army and to stay in power. There are several charges of corruption against her and her family.
Except for the high pitched rhetoric during the election campaign, there is nothing concrete that she has done to consider bestow superlative praises (such as "champion of democracy") on her.
People generally tend to avoid saying negative things about people who die in unfortunate circumstances but it is important for people and specially journalists to maintain level headed thinking in all circumstances and present balanced comments.
