So "kirk" as a verb can be interpreted as "send to God" is what I'm hearing

I would assume that using kirk as a slang verb would mean to "send someone to church" which is where they would have their funeral.

In the additional image in OP, it's used in reference to the assassination where he got shot, and the kid is using it to mean someone got sniped in the video game.

Yes, also see Odenkirk, which is from 'oude kerk' or old church.

Eeeeh almost, most germanic languages have a very similar word but "church" is only "kirk" in some specific areas.
The actual root would be kirikā from proto-west germanic.

In modern swedish it's "kyrka", pronounced roughly /shir-ka/

I once heard a story of whoever ruled the Netherlands suddenly deciding everyone should have a last name (and the deadline was extremely sudden), so you have a lot of nonsensical names from that region.

Carlson, Erikson (Xson), Slettenhar (slut's hair), Naaktgeboren (born naked) .etc .etc where a head of the household just brainstormed a literal shit post last name for their family (a lot of the vulgar ones were made in protest iirc)

In danish at least it is “Kirke”, so missing the -e, but nearly yes. I think it very much can be understood to have the meaning of Church. In german there’s Kirche, so again close.

In Scotland it's still commonly used to refer to a church

Go basically anywhere in Scotland and you can find a Kirk of some kind
