While the Bible only refers to specific acts by Biblical characters as "crying to Heaven for Vengeance", in Western Christianity, these references are expanded upon and treated as establishing a category of particularly serious sins. Along with the seven deadly sins and the eternal sins, the sins that cry to Heaven for Vengeance are the most serious transgressions against the Law of Christ.
“Behold, the wages you withheld from the workers who harvested your fields are crying aloud, and the cries of the harvesters have reached the ears of the Lord of hosts” (James 5:4)

The entire chapter is actually just warning rich people that their day will come eventually, but the specific part about wages is a sin seriously enough to warrant god’s wrath

Yeah but you can interpret that away:
It makes more sense, since it gives all these sins a common thread of oppression of the weak, rather than three sins about oppression, and one sin about doing butt stuff.
