So the spirit bomb (the most powerful one we had seen in the series at that point) was more than enough, and was a last resort for an out of energy goku This theory probably has some holes in it, but i’ve always enjoyed thinking this is the reason the spirit bomb doesn’t always work I also think that buu being a entity of pure evil also had something to do with why it wiped him out for good.

Does the spirit bomb only work on evil
The spirit bomb can be used to attack anyone
It doesn’t matter if they are pure of heart or pure evil However, the one who charges the attack must be pure of heart, as it could backfire on them. I think it's only someone who is good can wield it/bounce it back It's still a mssive ball of ki
If gohan didn't bounce it back, it would have killed him Don't play just to win, play for the fun of it The spirit bomb is a unique technique in dragon ball that harnesses energy from all living beings It symbolizes unity and hope, requiring the collaboration of the entire universe to defeat evil.
