But greed and malice are orthogonal concepts. Greed concerns ones selfish and personal desires and malice is intention to harm or seek revenge on others. One is concerned with the self and the other isn't. One does not necessarily imply the other. It is intellectually lazy to conflate the two.

That's one of those things that are only really true in theory. The word 'greed' has an overwhelmingly negative connotation.

No its not. If I am selling widgets for x dollars and making a handsome profit and I decide to raise my prices by 150% over night I am likely motivated by greed - to make as much money as possible. That it not way means I wish to harm people which is what the definition of malice is.

People get greedy in business all the time. That doesn't not mean their intent is to inflict harm other people.

Just because a word has a negative connotation does mean its has the same meaning as another word with a negative connotation.
