The dead leader's successor, Umar Rehman, will be unable to unite the already divided Tehreek-e-Taliban Pakistan (TTP), analysts say.
Despite Taliban leadership vowing to resume hostilities after an unprecedented ceasefire, signs point to rank and file Taliban members wanting to end the conflict.
Afghanistan's Ministry of Defence confirmed the death of Pakistani Taliban chief Mullah Fazlullah in what security analysts called a 'big loss' to the militants.
The former fighters said they 'no longer want to destroy the country and kill innocent people'.
The Taliban agreed to a cease-fire with the Afghan government for the first three days of Eid ul Fitr, giving many hope for lasting peace.
Newly trained pilots and combat aircraft provided by international allies are bringing about 'major changes' in the fight against terrorism, officials say.
The halt in hostilities against the Taliban will run from the 27th of Ramadan until the fifth day of Eid ul Fitr, Afghan President Ashraf Ghani said.
The Taliban are running scared and cannot sleep at night because of an undercover, Afghan government-backed group fighting the militants, local officials and tribal elders say.
A growing number of Taliban militants are reaching out to the Afghan government to find ways to end the decades-long conflict.
Taliban officials have been secretly seeking a truce, said Gen. John Nicholson, adding that there is a 'robust dialogue' within the group on the peace process.
