That isn’t what the angels were judged for. It was the sex between Angels and humans mentioned in Genesis 6. Not sodomy. Sodomy was part of the sin. I believe Sodom and Gomorrah were as the Bible says “exceedingly wicked”. Jude also mentions fornication. When the Angels went after strange flesh in Genesis 6, it was in direct violation of the Creator’s command to reproduce after one’s own kind. It also brought about a certain powerful race of hybrids whom God destroyed. I think these are the origins of the Greek mythological characters. Wild I know, and foreign to our thinking. But, the more I study it the more convinced I am. One of the chief sins of Sodom was their attempt to have sex with angels. I believe they were attempting some sort of spiritual treason with this act which sealed the deal with God. They did all the other things as well. But they lived right there in the middle of where the giant tribes lived and they knew them quite well (Genesis 14). Abraham went through and wiped out Giant tribes. Joshua ended up doing the same in the cities he destroyed, except some escaped to Gaza, Gath and Ashdod (Palestinian territory today). See Joshua 11:22 on that last one.
You'll have to try to convince me more thoroughly that 'sons of GOD" mean s "angels" in that chapter.
