One answer is that grant-writing is an evil deed. I don't tend to that belief, or the more plausible one that offering grants is an evil deed, but I think they're worth mentioning.

Not grant-writing per se, but grant-writing in excess of one's fair share (where "fair" is whatever you deserve - this would be a significant judgment point). The situation is complicated if everyone else is already grant inflating. It seems like a similar dilemma to that of preemptive violence: the line between self-defense and offense can be fuzzy.
