If you possess a pure soul you do not generate such thoughts. Degenerates that should be euthanized, as most of yourselves, obviously fantasize about such pitiful nastiness daily, one of the primary current sources of sin on planet earth, thus aligned with evil machinations.

I suggest you fix yourselves before you get fixed, but I would prefer you continue in your errant ways for a little while longer so your unsuitability for this planet is fully documented with these digital systems, so you can be quite cleanly disposed of with zero karmic losses.

I suppose you deserve a bit more explanation than that. Yes, DNA overlap occurs with incest, so you should avoid such things by default, but it goes beyond that. As a parent you are supposed to feel absolute loyalty to your offspring, to the point you would gladly sacrifice your own life to preserve theirs. Preserving the sexual integrity of those offspring exists under that umbrella of protection. A truly sentient human being that deserves to be a member of this society, moving forward, understands this automatically, without outside instruction, such as from me to you in this moment. Hopefully that explains enough and you understand your doom when you land down in purgatory or worse.
