And this is another example of why violence does not work to ruin religions. They simply pray to that beady-eyed monster of a god of theirs for strength. And I am sure that abomination harvests the energy, both from the victims and those who pray for them.
Did this disrupt the religion? No. True, it disrupted a few boasting sessions. But they are simply going to hold them elsewhere, with no loss. This happens every time a "place of worship" is ruined, whether by a shooting, a fire, a natural disaster, or whatever. It simply pulls the congregation together (along with nearby congregations) to rally for those affected, which is the exact opposite of what you want if you are trying to ruin the religion.
This is no different in the scope of damaging the congregation than an incident I remember as a cat lick. When I was about 8, the church we went to had a major fire. Did that ruin attendance? No. Instead, they simply found an alternate venue to hold that abomination, and donations went up significantly. This is the opposite of what I would have liked, had I wished to ruin the cat lick church. It is no different with synagogues and mosques, or any other church.
The better approach would have been to expose the fallacies of the religion, or even the whole bible. No one is going to die if everyone realizes that jesus is nothing more than the archetype of the perfect slave. Rather, people would stop attending those boasting sessions (and church in general). In this scenario, donations would stop and people would simply abandon the church. That is how to ruin a church, and there is no risk to innocent lives as with a fire or shooting (nor is there a risk that donations would go up along with prayer, for joke-hova to harvest).
