Big Mom : Ally or Die?

Big Mom will die or become ally..?
This is big question..
So big that makes us wondered..
Capone plan for head off Big Mom..
The wedding day started..

Big Mom will die..?
Or Big Mom will become Luffy's new ally..?
Let us predict more on this topic..

Do you guys want Big Mom to die in this arc..?
Or do you think that she will not die because she will help SH in future..?

For me..
There are two consequences that might happen..

i) Big Mom die
If Big Mom the yonkou die..
Who kills her..?
Who will get her title as yonkou..?
Capone don;t want the title..
So who fit for that title..?
Luffy..?
Vinsmoke Jajji..?
A new representative from Underworld community (maybe Mother Caramel points someone from Underworld)..?

ii) Big Mom live on and become SH's ally
If Big Mom the yonkou alive..
What kind of plots that will makes her changed her mind toward SH..?
Who will make her change her mind..?
Is there sacrifice to make Big Mom understand the situation..?
Could Big Mom understand the meaning of winning but loosing a lot more..?
Could Pudding be Sanji's bride..?
The relation between Big Mom & Vinsmoke will be okay or they become enemy..?

For the question who will make Big Mom change her mind..
I got three theories on that..
a) Pudding make a sacrifice to save Sanji.. This will make Big Mom see that almost all of her children don't love her because she was a bad mother to them.. We can see Big Mom hates to see Pudding's third eye.. Praline & Chiffon hates Big Mom.. All the children just want to serve her.. Because she's the yonkou and she will not hesitate to kill them (like she kill Muscato because of her craving symptom).. Or Pudding makes used of her DF ability (or she awaken it) to re-write all memory so the fight will stop)..
b) Dogtooth mentioned that he foresaw something from the future.. They will lost in this fight.. He tell her mother to stop before it too late for them.. Maybe he saw Big Mom died and few of his siblings also dead because of Big Mom's plan..
c) Someone else comes and disturb Big Mom's plan.. The fight that Big Mom plan now changed because of that someone.. That someone is Kaido.. He will ambush Big Mom so that he will get his hand on the road poneglyph hidden by Big Mom.. Maybe he also knew that Pudding somehow will be the important key to reach Raftel.. He will kidnap Pudding.. This will makes Big Mom want help from others.. Sanji will volunteer to save Pudding.. So SH will agreed to fight Kaido.. Big Mom will become SH's ally..
