The family belief in religious cult that when twin are born they should get rid of one for the family to not have misfortune , they spared the two twins so the father feel guilty and that it his false his son and wife died cuz he did not kill the other twin , so while he became unstable due to his own religious beliefs and guilt .. the other twin his son also unstable cuz he always wanted his father love and attention that he saw was given to the other twin , and after his twin brother died he thought he was gonna finally get that love he earned for but cuz it didn't happen he tried to force it out the father by telling him his beliefs are wrong and implant new beliefs into him , the story fucker up but that pretty much sum it up .
so the dad became unstable just cause his kid and wife died? or maybe because his other son confined him and raped him daily? :) that would make you mentally unstable too u know.
i wouldnt even be surprised the son had a hand in the mom's and his brother's death,or is it really just twisted fate for the dad?
interesting read either way, hoped there was more.
