Again, you are runing away from the question and trying to answer a different question.
It is fact ( which you can not deny) that Sunni and Shiaa have two very different understanding on the fate of Islam after the death of Mohhamad.
Now, there ideaology can either come from their understanding of Quran or there was nothing in Quran to tell them what to do and...
Now, if it is the first case, then one group has a wrong understanding of Quran. So Which one is it?
Understanding right after the death of the prophet was clear enough that the 4 khalifs never fought with each other (not as you claimed in error earlier!)
The understanding was there even during time of Imam Jafar (ra). He even mentored the greatest of sunni scholars. so there was no deviation. The problems you see now is political and lack of understanding. it took moslims about a 1000 years to have these sects, STILL, there is not "right or wrong" sect, we all have our own understanding of religion, it is not so black and white. your "black and white" attitute shows lack of understanding here.
If you insist on your black and white version of the world, I must ask you, which one of these sects in your 150 year old bahai religion is correct?

People of Bayan or Bayanis
These are those who believe the true successor of The Bab is Mirza Yahya Subh-e-Azal
and not Mirza Hussain Ali Noori (Bahá'u'lláh).
Daheshists These are those who believe that their leader, Dr. Dahesh – Saleem Moosa El-Awshee is the "Return" of The Báb (Ali Mohammed Shirazi).
Essence of The Bahá'í Faith These are those who believe in the coming of the Third Manifestation after Bab and Baha’u’llah.
Unitarian Bahá'ís These are those who believe after Baha’u’llah, his younger son Mohammed Ali was his true successor.
Questioning the Will and Testament of Abdu'l-Bahá 1. Free Bahá'ís
2. Reform Bahá'ís
3. New History Society
These are those who believe that Will and Testament of Abdu'l-Bahá is a fraudulent document doctored by Shoghi Effendi Rabbani.
Continuation of Guardianship
1. Orthodox Baha'is (followers of Joel B. Marangella)
2. Baha'is Under the Provisions of the Covenant (followers of Neal Chase)
3. Heart of the Bahá'í Faith (followers of Jacques Soghomonian)
4. Tarbiyat Baha'is (followers of Rex King et al)
These are those who believe in continuation of Guardianship.
Heterodox Bahá'ís These are those who believe that the Guardianship ended with Shoghi Effendi and at present UHJ is the true leader.
Followers of 5 Elders These are those who believe that the UHJ requires an infallible Guardian in line with the teachings of Bahá'u'lláh and Abdu'l-Bahá. It looks like the Baha'i denominations will succeed in mounting a significant challenge to the mainstream Haifa-based Baha'i Faith. On the other hand main stream Haifa Based Baha’is are putting more pressure on their UHJ to clarify the concept of Guardianship, rather than asking them to shun the Covenant Breakers. The recent court case done by the Haifa Based Baha’is on their two other denominations has further internationalize the issue of Guardianship. It looks like the balance is tilting more towards Guardianists. If current trends of infightining continue, it is possible that Baha'ism will suffer from more divisions. It has to be seen.
