Why is sodomy not considered a greater sin than murder, even though its corruption might be greater and could lead to the annihilation of humanity, and does the gravity of a sin depend on circumstances and conditions?

Scholars have differed regarding the preference of fornication over murder, with murder being the more correct (more grave) opinion. They also differed regarding the preference of fornication over sodomy, with sodomy being the more correct (more grave) opinion. Ibn Hajar al-Makki mentioned that fornication with a neighbor's wife is among the greatest major sins, and that the more correct view is that murder follows polytheism, then fornication, and the most heinous type of fornication is fornication with a neighbor's wife. Then Ibn Hajar stated that fornication is greater than sodomy because it leads to the mixing of lineages, though this might be countered by the fact that the prescribed punishment for sodomy is more severe. As for the words of Ibn al-Qayyim, they are not explicit in stating that sodomy is greater than murder. He says: "There is no evil among sins greater than this evil [referring to sodomy], and it is second to the evil of disbelief, and perhaps it is greater than the evil of murder." So the evil of sodomy might be greater from one perspective, and the evil of murder greater from another perspective. The conclusion is that murder is a greater sin than sodomy, according to the more correct view, and that sodomy is a greater sin than fornication.
