As I mentioned, Goku received a surprise attack from Piccolo that punctured a vital organ, and even without Zenkai he could still stand up. Goku's physical resilience is absurd.
So is Akuma's. Even more so since Akuma isn't subject to pain like Goku is.
Btw, would that mean that Akuma would immediately go in for the kill with sloppy kicks? It would be really bad for Akuma if he treated Goku dryly, because in a direct kick like in the case of the scan he would have his movement totally read and copied by Goku's PM. Also, Goku fought Piccolo Daimaoh who is naturally Bloodlusted, he knows how to handle opponents like that.
That scan was to showcase his ruthlessness and lack of hesitation in combat, not his skill (Since that scan is from early in his fighting career).
Also you use bloodlusted for Piccolo, but I don't think you know what it actually means officially on VsB. You're bloodlusted when
you fight with no inhibitions, only care about winning, feel no fear, and are willing get hurt if it means winning. Akuma has all of these qualities. King Piccolo does not. Piccolo regularly tortured Goku by smushing his face with his fist and dragging the first fight longer than he needed. He gets scared by the Evil Containment Wave and when Goku starts kicking his ass the first time. And on top of that, used Tien as a hostage to keep Goku away and attack him at a distance.
At this point, Goku has not fought a bloodlusted opponent before and villains like Tambourine, Piccolo, and Tao Pai Pai took it causually when they fought Goku the first time.
What's in character for Goku to do is to copy the opponent's fighting style and combine it with his own style and creativity. The fight against Tien is an example of this, there is no way to say it's totally OOC.
Your scan does not at all support what you have said here. All Roshi said is that Goku is reading his opponents moves and planning ahead which attacks would be more effective. Not copying or even combining. If you've ever dabbled in RL martial arts, reading and planning for your opponents moves is pretty standard and there's really no reason why Akuma wouldn't be able to read and counter Goku's moves as well. You're acting like Akuma just stepped into a dojo for the first time and started throwing "Sloppy kicks". Akuma is a legendary fighter.
Me and Saman keep bringing up that Goku doesn't copy fighting styles and techniques that often, and more tries to counter them with his own techniques and styles. For some reason, you're ignoring it or just don't understand. The point wasn't that Goku couldn't counter some of Akuma's attacks, the point was would he even have time to do it and could he even effectively counter the teleporting, Intangibility, and the speed amp.
On top of that, he's faced opponents similar in power to him and didn't immediately overwhelm them with his martial arts and Zenkai. I.E. Yamcha, Tien, Master Roshi, Yajirobe.
Goku is a genius when it comes to martial arts. He's a prodigy, but he's not a martial arts god (At least not yet ;>)
Wouldn't Goku having mastered God Chi be a practical example that he could copy Akuma's chi in that situation?
I don't see how morality could change anything here. Akira himself mentioned that Goku is not a hero, he only wants to fight the strongest people, and yet he fought with intent to kill several times, as in Piccolo Daimaoh's own case.
Uh, no. Goku was only able to use God Ki through the SSG ritual, not because he actually learned it. The Satsui no Hado is more like the evil/dark side of chi and emotions that can be released with killing intent and the will to win. With Goku having a pure heart, there's really nothing to release there even if he does have the intent to kill. Goku is not a hero, but he is pure good.
There is too much reasonable doubt to confidently think Goku could utilize the Satsui no Hado with his pure heart and the dark nature of Satsui no Hado. Even if he could utilize it, he'd go berserk. And we ALL know how he handles going
berserk. Even someone as focused as
Ryu becomes single-minded and predictable when berserked by the Satsui no Hado.
I really don't see Goku winning
