Dragon Ball Z1996

[Krillin is going to kill Vegeta]

Goku:
Stop! Don't do it!

Krillin:
Goku, is that you? We have got to stop this guy while we have the chance. He's... he's pure evil!

Goku:
No, listen. Just let him go, Krillin. Show him what it means to be merciful.

Krillin:
Merciful? But Goku, he's...

Goku:
I know what you must be thinking, but believe me, I know what I'm doing.

Krillin:
This is the guy that threatened all the people here on Earth. Surely, he'll try to come back and destroy us again. I just don't think it's a good idea to let him escape now that we have a chance to stop him for good.

Goku:
By doing this, we're showing him that there is another way, a better way.

Krillin:
Goku, I don't think this is the kinda guy that can learn a lesson like that. He'll just think we're weak. It won't change him at all!

Goku:
Don't be so sure about that, Krillin. It wouldn't be the first time something like that happened. Think about it. When Piccolo first came to us, he was just as evil as his father had been. He nearly destroyed not only me, but the entire planet. And now...

Krillin:
And now he's one of us.

Goku:
Right. And if someone as evil as Piccolo can change, I think anyone can. Vegeta deserves to have that same chance. And by showing him that the people of this planet have compassion and can show mercy, maybe he can learn to show some of his own. Piccolo learned. And now he's not only a powerful ally, he's also a good friend. He even took care of Gohan while I was gone and traded his own life to protect him. Who knows, Vegeta might do the same thing for one of us someday.

Krillin:
Grrr...

Goku:
Krillin, please. I know this is the right thing to do. You've got to trust me.

Krillin:
But the Saiyans killed Yamcha... and Tien, Chiaotzu! I can't let him get away!

Goku:
Don't do it, Krillin. I know it seems like justice, but it's not right. If you strike him down, it will only show that we aren't any better than he is. It means that they've won, no matter what. He's strong... don't forget Krillin, I am a Saiyan, just like he is. [Krillin drops the sword]

Goku:
Thanks Krillin, that took a lot of strength and courage. I'm proud of you.
