Pink Chidori

She is most definitely a terrible person, just like everyone else in this story.

Well, you are entitled to your opinion of course. I disagree, but to each their own. :)

It's more believable that she would have forgotten all about Naruto than for her to not forgive Sasuke for killing Naruto. Sasuke tried to murder her and Naruto many times, tried to kill her friends, her family, her mentor, her teacher, the kages, he is already in part responsible for the deaths of tens of thousands of people, and Sakura didn't care. She wouldn't have cared if Naruto had died, the ending showed that he really didn't mean much to her in the first place. 

You're free to have your own feelings about it, however I do disagree that Sakura would not have cared, or would have forgotten Naruto. I do not believe that is something she would do at all. Sasuke did do many terrible things and all was forgiven on both her and Naruto's end. Though, I think that is because Kishimoto never allowed Sasuke to cross that line and actually do it. He tried (and failed) to murder them both. He threatened the lives of those she cared for. Now obviously I'm not trying to say that him doing those things were not wrong nor justifiable. However, I think that Kishimoto probably found it easier to have Sasuke be forgiven for crimes he almost committed against those who cared for him, rather than having him being forgiven for actually commiting them. Just as I do not believe Naruto would forgive Sasuke for killing Sakura, nor do I believe Sakura would have forgiven Sasuke for killing Naruto. Despite everything Kishimoto has done with his writing, the one thing I do not doubt is that Naruto and Sakura care for each other and certainly would not be okay with one another being murdered.

Sometimes I think Kishi should think before saying something that could be considered controversial like this.

Good. Save any more possible harm from being done. Though the damage is already large on its own.

Back in the old days this will be legit. But currently even Orochimaru can be hokage and it'll be treated like nothing.
Plus Sasuke is like some sort of idol atm.
He can be hokage if he really wanted to. But that will mean staying with his family.

Hmm, true.    I still can't believe Orochimaru is just chilling outside the village like he didn't commit numerous crimes over the course of his life, including attacking Konoha. But hey, I guess if the hero of the story considers someone like Obito the "coolest guy," and Sasuke can be forgiven many times over, I can't be too surprised. So I guess the best reason is because Naruto is main character and wanted to be Hokage, it was his biggest dream that he talked about all the time, so it had to happen I guess. Or heck maybe there wasn't even a reason  and Kishi just rolled with it.
