In general, I say no.
If you cheat, then you are breaking that trust that your players have in you (even if you get away with it without them noticing!). Your players are expecting that you roll honestly and even if that means the death of their PC due to the whim of the dice they will respect you more for this than for fudging the roll and giving them a break.
I don't cheat when I GM, but then again, I've never got myself into a situation where all the PCs are going to die. An inexperienced GM may have more of a tendency to accidentally do this.
If I had to "cheat", then it wouldn't be fudging the dice rolls, I'd probably have an NPC step in and save the PCs or something. But even then, this can irrate players if they are "let off the hook" all the time. Players want to feel that their PC's lives are threatened and that death is a very real possibility. One of the great things about RPGs is that they're not exactly stories; they're also a simulation of life's randomness. In a story the author can have his hero get out of all sorts of scrapes, but in an RPG this isn't necessarily the case.
