Islamic State more radical than Taliban?

 ISW:

Key Takeaway: Islamic State-Khorasan Province’s overarching objective remains to undermine and ultimately replace the Taliban government. The group’s recent attacks are part of its effort to delegitimize the Taliban at home and obstruct its efforts to normalize its government internationally. These attacks on countries neighboring Afghanistan signal to international jihadists that Islamic State-Khorasan Province (IS-KP) is both willing and able to attack internationally. IS-KP is also attempting to attract local Uzbek and Tajik jihadists by signaling to them that it will support their efforts against the Uzbek and Tajik governments.

IS-KP is increasingly targeting neighboring states as part of its campaign to undermine and overthrow the Taliban government. The group has carried out attacks in Tajikistan, Uzbekistan, and Pakistan in recent months, some of which were part of a global Islamic State campaign of attacks called “Revenge of the Two Sheikhs.” The attacks in Tajikistan and Uzbekistan demonstrate an increase in IS-KP’s willingness to strike Afghanistan’s neighbors. IS-KP’s growing strength in northern Afghanistan poses an increasing threat to neighboring countries. The Taliban government continues to downplay the IS-KP threat, and its recent military deployments indicate it is prioritizing the threat from non-IS opposition groups instead.

There seems to be no upper limit on how radical Islamists are willing to push their agenda.   The people in the region should reject both extremist groups.
