Your kindest moment in gaming?

I usually play Medic in TF2, and I heal everybody, all classes and skill levels.
I also try to teach new players the game or give tips to people on how to improve, if they appreciate such things that is.

WoW, definately. Just going to areas for lower levels and helping them do... well, anything. I'd often just show them where a rare spawn was, because I was a kind of fanatic about hunting rare spawns, and I just generally helped some lower levels.

Also there was this oen time in Bad Company 2, where I for some reason I've now forgotten, was looking the opposite way and aiming my Type 88 with 12x scope near one of my teammates, who was also sniping and facing my way, oblivious to his rear. Suddenly, I see a guy appear behind him and prepare to end him, so I countersnipe his head off, prompting the teammate to get angry into the mike saying how I was trying to teamkill. Then someone else said "Man, look behind you". Needless to say he muttured something that may have been thanks and continued playing.
Also I like healing, reviving, or restocking my teammates on BFBC2.
EDIT:

Halo 3, CTF. So the third time, when I had the flag next to our capture point, I just dropped it and stood back for him to take and score.

I do this too sometimes.

Running out of the safe room to save my team who were all downed by a tank that spawned just after I got to the safe room, and the time I held off the enemy team at great cost to my K/D spread to cover the flag carrier in halo 3.

Plus multiple times when I've almost literally swam in bullets to revive people in BC2.

Come to think of it, I'm a pretty kind person in gaming. I must stop, it'll ruin my reputation.
