If suffering is in fact primarily caused by evil and evil is caused by Satan, then most suffering is causally connected to Satan somehow
If Satan is inherently a liar, known as the father of lies, then all our suffering is based on lies
Furthermore, these lies lead to self contradictions as in the Bible we see all satanic manifestations, especially in humans, as having some kind of internal self contradiction
Therefore all suffering or at least mentally, is due to self contradiction
If you want to be free from suffering, the use of logic to spot self contradictions in your thinking and thought patterns is the easiest way to freedom.
Evil is caused by Satan
Satan is inherently a liar
Therefore, logic leads to freedom from suffering
