It is. You have the incredible abilty to judge what is a fact and what is not, according to what you want to prove or rather impose. He knows he didn't need to fuse, but without Mr Popo proposal, what was going on ? He prefered hide his SSJ3 and let the earth burn ? okay, you're in Goku's head, it's a fact.That's not an interpretation, it's a straight up fact. Goku didn't need to fuse, he knows that. Does Goku's statement about him being able to beat Fat Buu during his fight with Pure Buu mean nothing to you?
I don't understand the aim of your last question.
1- Yeah, so without Popo earth would be destroy. Good point Goku !He suggested Fusion against Innocent Boo because he didn't want to use Super Saiyan 3, since he didn't want to waste his time on the Limit World.
He didn't want to kill Boo because he wanted to make the kids stronger than him, because he was supposed to stay dead. So he had to make new successors, since he thought that Gohan was dead, which is why he lied about not being sure if he could beat Boo.
He lied to Vegeta that they couldn't beat Evil Boo because...?
2- It's not explaning why he lied to Piccolo. Or I don't understand. There's a contradiction in your theory : if Goku really wanted to hide his SSJ3 and let it to the boys when he talked to Krilin and Piccolo, why does he proposes a fusion with Bejita or Gohan ? It implies him. And the excuse : "if he had said that he was confident that he could destroy him, they would ask him to do so, they would try to convince him. He didn't want that, he wanted them focused on solutions that required their own power."I disagree. Piccolo is not stupid, Goku already tell him that he didn't know, which implies he could have, may be. Piccolo understand at this moment that it's a gamble. But Goku still liying.
He lied to Bejita because Fusion was the safer way to kill Evil Buu, and he has to convince Bejita to fuse.
