Actual sin
Venial sins are sins that do not meet the requirements for mortal sins. The act of committing a venial sin does not cut off the sinner from God's grace, as the sinner hasn't rejected God.
Some Orthodox and Protestants Christians hold similar views.
We can see why sin is universal when we understand the terms God motivated to describe sin. Because rapist, murderer, drunkard, the robber and child-abuser are obviously evil, we readily agree that they're sinners. In our hearts we consider ourselves to be respectable citizens since we do none of those things. These terms, however, bring us face to face which it is not always obvious.
Moral evil as considered from a standpoint. Sin is regarded as the deliberate and purposeful violation of the will of God in Christianity and Judaism. See deadly sin. As a Christian, I think that is a sin against God.

Kings compounded their sin by persecuting the prophets who pressed God's covenantal claims and sometimes rejecting. Ahaz even spurned God's free offer of deliverance from invasion; he thought he had arranged his own deliverance through an alliance with its gods and Assyria. Not all kings were crass; many strove to serve the Lord as they chose, in forbidden manners (Jeroboam I, Jehu, and other northern kings). Others tried to serve God and the Baals at once (Solomon, get more info the last kings of Judah, and lots of northern kings).
The state of our Web is a consequence of picking advertising as the default model to encourage services and content. Through successive rounds of innovation and investor storytime, we have trained Internet users to expect that everything they say and do online will be aggregated into profiles (which they cannot examine, challenge, or change) that form both what advertisements and what content they see. Outrage over experimental manipulation of these profiles by social networks and dating businesses has resulted in heated discussions among the technologically savvy, but has not shrunk the user bases of those solutions, as users accept that this sort of manipulation is an essential component of the online experience.
