To those on this sub that believe she killed them?

Hey all,

To those that believe she killed the kids, why do you believe that beyond her being who she was of course.

• why would he have said he did it?
• why would he of stood by the fact he did it?
• why would he of dumped their bodies in oil tanks like garbage?
• why would he still all these years later stand by the fact he killed the children?
• why would he cover for her then let alone now?
• why would of he of given very precise, gory, unimaginable details about how his children died and how he committed the murderes in a private letter ?

I don't understand why people think this?

She in life was so awful to those children but there is nothing that has made me think she killed them.

He would of kept singing if he thought he could of got away with the lies they put in his mouth.

He killed his children.

Am I wrong?
