The cartel just reassessed their output as a result of the continuing war and decided to increase output.
And OPEC cares a lot about externalities. They know that pushing oil prices high enough will cause a recession which leads to less money for them. (They learned this in 1979). So they try to maintain a healthy but not runiously shortsighted profit.
It's purely free markets doing what they do - trying to optimize for the point where profits are highest by raising prices until demand drops sufficient to level off total profits. Externalities be damned (environmental, social, economic, etc.)
