Cowl appeared to do it because at the time he felt like he had no choice, it was a last resort. That's how I remember it anyways. Maybe he doesn't want to do it, and only felt he had to at the time.
For someone who was really reluctant, he went through a lot of trouble to get the information to do it..
I believe it's because there was a race against the Kemmlerites wasn't there?Maybe there was more to the Darkhallow that we aren't aware of. Maybe it can be done every 13 years or something.
I thought Cowl was a Kemmlerite, at least Kumori was and she tried to stop Harry from stopping Cowl.

There is a lot of preparation if you want to do it well. They helped each other with the preparations and tried to kill each other off as well.And there was all the plotting to keep the white council occupied during the event. Cowl has to do everything by himself now.
Of course I just remembered. He doesn't have Bob, OR The Book of Kemmler... So he probably couldn't try it again. The spell is probably to precise to do from memory. that would explain why he hasn't tried it again too.
Except that once read another necromancer immediately understood and Harry understood as well. Apparently once you know it is not that difficult to remember
Wait how do we know cowl is working with outsiders? I must have terrible memory..
