Genuine question.
Do they positively want Armageddon to happen (and are actively seeking it to hasten its arrival by any means) or do they merely believe that their god is going to make it happen at some point of his/her choosing?
They
want it to happen because they believe it will hasten the second coming of Christ, before which they will get beamed up to heaven by gawd in the rapture. It's an integral part of evangelical doctrine. It's what making Jerusalem the capital of Israel is all about, it's part of a prophecy that will lead to it all kicking off, or so they think. The prophecy includes building a 3rd temple in Jerusalem and making Jerusalem the capital of Israel would help with that. They think that then a dignitary will enter the temple and declare himself to be the anti-christ. Many used to think it would be Blair. I know, it's bat shit crazy, but it's what they actually believe.
Generally speaking of course, I'm sure there's many evangelicals that are more considerate of others, but asides from that, yeah, they
want it to happen. And Pence is pulling strings to try and force it. I don't think that they'll get what they want, but that they even want it is enough. That they are trying to force it is worse.
And a lot of people think Islam is the only dangerous religion...
