Deku Child...

The deku butler came a loooooong way to pray at the statue.I thought ALL the curses were broken afterwards? :-\

It said that Skull Kid killed that Deku child to make the Deku mask. So there was probably no way of bringing him back. Poor deku butler. :(

Look at it this way.  Link does something different everytime he sets back time.  However, everyone else does the same thing unless Link interacts with them.  That means Darmani still dies in his attempt to save the Goron village and Mikau still dies from his attempt to take back Lulu eggs.  Of course, those weren't exactly curses caused by Majora's Mask.  So I'd assume the curses were lifted.  Or that Link went around Termina using his Song of Soaring and lifting all of the curses before fighting Majora.

As for the Deku in the beginning, I believe he was killed.  And you can't bring the dead back to life.  You can reanimate them, but they won't be alive.

I just look at it this way: Link only goes back three days in time. Anyone who died before those three days, or got in a situation that would inevitably cause his death later, cannot be saved. The Deku child was killed before those three days, Darmani was and Mikau got in the earlier described situation.  Being killed is not being cursed. Curses can be lifted, dead = dead.

And for the fact all things Link did for others happened in the end: I think this has something to do with Termina. It's obvious that place has a strange link with time (Clock Town anyone?) and therefor I think that influenced time in MM. Or it could be that is the true effect from using the Ocarina Of Time. After all, Link always used the Master Sword before to travel through time, not the Ocarina.

Yeah, evil once again rears its ugly head in a horrible fashion. Makes you wonder... People arent born meen, or evil.. What happenes to them that warps their mind so?

[LadyNintendo]

Fear and betrayal can do nasty things. Or even the most stupid of accidents. And then there's the wish for power.

[Princess Ruto]

or a wish for help if your in the situwation like the deku child

In TP there was a cut scene where the light spirit Lnayru shows Link a telepathic movie of what could happen if he's not careful. It shows Link, and his friends finding the dark power, and then turning on eachother in hopes of ruling it. Power does nasty things indeed.
