Have you no pride?

[Eomer of the Rohirrim]

I hesitate to call the attribute of pride a necessary evil, but this is possibly what I'm getting at. Can we imagine a situation where no hero had pride? Would this make good and bad deeds impossible?

Perhaps the solution is a reply to whoever compiled the 7 deadly sins. Did you sir, use the term 'pride' in a vague sense? Because this discussion seems to be leaning in favour of pride as necessary.
