No, I don't think greed is human nature. Greed is taught.
Yes and no. Greed is very much part of nature in general, not just human nature. Usually it's not greed to pure excess, but greed beyond the perceived need. By that, I mean the line between self-interest and greed can be fuzzy and not everyone is going to agree on where they/others fall. You can want more than you can ever realistically use, but within a range that could also provide for friends and family, for example. Depending on the definition, or who you ask, that could be greedy.
The level of greed some/many humans display is very much taught, however.
