Makes 0 sense that no one wishes for the best Earth fighters to be immortal

[Sensiblesaiyans]

You would think given that the earth is constantly under threat by an evil alien every decade or so that someone from Goku's team would secretly gather the Dragon Balls together and wish for Son Goku, Vegeta, Piccolo and Gohan to be immortal. The fighters will never know about the change until a life and death situation comes up and I'm sure they will be thankful when the immortality kicks in instead of being bodied and killed.

This, should have been the logical plan of action by some of the lesser powerful Z-senshi like Krillin, Yamcha and Chiaotzu when Trunks told them that the z-senshi were all going to die in 3 years by the androids. This way you at least have a safety blanket in place if the fighters come up short in battle. For the very least, they could have given Piccolo immortality so he doesn't kick the bucket early and make the Dragon balls go inert.

And why oh why has no one wished immortality for dende given the dragon balls become powerless if he dies? This should have been done already given how many times he has brushes with death. And an immortal healer would legit make him far more useful on the battle field and remove the possibility of him getting death beam from a stray ki attack.

Immortality is considered to be an "evil" wish in Toriyama's Dragon Ball.

Zamasu wished for immortality, and Vegeta (when he was evil) and Freeza sought to attain immortality.

There was also that Garlic Jr. gremlin or whatever he's called from non-canon Dragon Ball who wished for immortality.

Since Dragon Ball at its core is a story about self-improvement, training, and spiritual growth, immortality is considered to be an "evil" wish because it is a cheap shortcut to power that results in the user getting more depraved and self-complacent. Like Zamasu who never trained anymore after he got immortality and never tried to improve his skills and tactics because he could just face-tank any attack and survive without a scratch.

These characters aren't ideal superheroes. They're human martial artists.

Using their wish to revive those that get killed, that is very heroic and selfless thing to do. They could wish for things that they want, instead they make selfless wish to help others.

Training future warriors to the protect the earth, while sacrificing the chance to fight a powerful enemy is selfless, especially is said person likes to fight powerful enemies.

Being human means they're capable of being selfless, just as they are capable of being selfish. That doesn't mean they would sacrifice their individuality, autonomy and privacy for the sake of a platonic ideal of being a protector of the planet.

Why would they rig the game the love playing? it's a sport to them, not a job.

Being immortal also means living forever, it's not just plot armor, it's never dying, not even of old age thousands of years after the wish. Goku might think it's all the same, but Vegeta would definitely hate outliving Bulma and Trunks.
They are supposed to be characters, not soulless weapons.

You acting like the dragon balls can't undo a wish. If the DB can give you immortality then it can strip it.

And I'm not saying the benefactors themselves do it but other people who likely dont see it as a sport and want to live. People like krillin, yamcha and chiaotzu who probably has strong survival instinct and dont want to leave their fate up to chance.

It makes total sense, the story would be boring if that occurred!

[super michael]

What doesn't make sense is why didn't Master Roshi wish for eternal youth like Piccolo Daimao. Master Roshi wanted to wish for girls, instead of eternal youth.

Dying isn't that big of a deal in this world. Worst case? They get to chill with King Kai or in heaven.

It also stagnates growth. And immortal can't be pushed in ways mortals can. They don't break their limits in dire situations. Everything would just become a war of attrition.
