Weird for someone who makes decent theories to have such bad comprehension here. Where did I say I hated Sabo? Pointing out that Ace died quick despite being Luffy's brother and that Sabo shares a parallel, and that you're first comment was purely wishful thinking that equals character hate? Now if you feel the urge to continue spouting of irrelevant nonsense like calling people Sabo hater, not much I can do to slow you down just do so with the thought in mind that you look incredibly childish.
The question could be asked why did Oda introduce Ace just to have him be captured and executed. Ace showed a lot of potential to be a cool ongoing character with his relation to Luffy. The next thing we know however, is Ace is being beaten by BB and taken to the WG for execution. Yes I agree it would suck but Oda did it before. Which is the point Shon93 seems to be missing.
Ace's death was based on 2 arcs, Impel down arc and marineford arc, so Sabo just suddenly getting killed randomly without an arc based solely on him would be stupid.
Ace was introduced in the Alabasta arc and died in the marinford arc. Plenty of more time than Sabo , so you can't compare him dying to ace's death
Because of Ace death Luffy chose to take a 2 year break and train to get stronger so he can never lose the ones he loves again, so Ace death did have a significance
Sabo was presumed dead until just recently there is no point in killing him off so quickly after just bringing him back into the manga. Yes Sabo can die but the chances are highly unlikely
