[DBS] Why the hell are the Kais so weak?

Like seriously, the Kais are the life line to the god of destruction, but the Kais are pathetically weak. Why is the life force of something as important as the god of destruction tied to really weak gods?

Because they don't need to be strong. Whose likely to be stronger, the gardener who tends the plants, or the thug who tramples them?

The Kai's aren't there to fight. They aren't even there to protect. They exist to create. Whereas the Gods of Destruction need to be able to confront and destroy anything and anyone, the Kai's have no such need for confrontation. 

It also helps reign them in. If they were strong enough to stand up to a God of Destruction, they would probably try to prevent them from doing their job. 

Al of that said, let's not forget that the Kai's ARE strong. Even King Kai was stronger than Goku when he first trained with him, and Kaioshin is stronger than most of the Z Fighters. They're stronger than most living things... They just don't need to be obscenely strong, like the Gods of Destruction and Angels are.
