If you could just provide me with a ”yes” or ”no” answer that would suffice insha’Allah. My friend made an oath and broke it, but it was in a fit of anger. Let me tell you what was said:
In the Name of Allah, Most Merciful and Compassionate
Yes the kaffara is required as he did not fulfil it, even though he was in a fit of anger.
And Allah knows best
