Reentering a tournament is exactly the same as late registrering. If you got coolered and stacked in the first few blind levels, there is no objective reason to not reenter. There was probably a reason, why you decided to play that tournament in the first place, and that reason is still there.
Not reentering in that situation is the same as leaving a cash game, because your KK ran into AA after 10 hands, and you got stacked. We should be bankrolled for the games, we play, so firing another bullet at either a tournament or a cash game should not be a problem, when we just got unlucky.
If the tournament has been running for several blind levels, it depends on, if you like to register late and start with a relatively short stack. If you do, then reenter, if you dont, then play the next tournament instead.
