The idea that EP would never have killed the guests considering the subsequent scrutiny is easily belied by all the times it has been known to happen.
Exhibit A: Lori Daybell and two other adults killed her own children, buried them in one of their backyards, and then went about their lives as though it never happened and as though they would get away with it.
Killers make dumb decisions everyday, that's why they get caught. It's backwards to try to credit them with innocence for those dumb decisions.
I think when murderers do these outlandish crimes, there's possibly some variables in thinking:
- They don't care. About themselves, the future, their life, others' lives, being in prison or put to death. They've thrown in the towel and are exacting anger / revenge;
- They're profoundly mentally ill and feel compelled by delusion / psychosis;
- They're extreme and fundamental in a religious or spiritual or political way and believe only god can judge them or that they are doing god's work or killing for the greater good;
- They're obsessed, ie a form of OCD / compulsion and get 'tunnel vision' and focus so much on the crime and the eradicating particular people, they 'forget' to do much or any of a cover up;
- They're so filled with rage and anger that their mind is hijacked and rational logic has gone out the window and ditto they forget to do much of a cover up or think through the outcome;
- They believe nobody's looking, nobody's particularly interested, nobody's going to pay attention and alert authorities even though several people may have died or they're on a spree (this can especially happen when the victims are vulnerable - ie recent migrants, or transient, or vagrant, or drug addicted, or very elderly, or street walkers / prostitutes etc on and on;
- They have a personality disorder and a personal history sufficient that they've learned over time they never get consequences from their deceitful actions and they have no moral compass or empathy;
- They have a personality disorder sufficient that they cannot and do not connect 'action and consequence' and 'cause and effect' and are unmanageable and unaccountable people who do what they want when they want;
- They are so grandiose and manipulative and lack empathy to a point they believe anything they do they can easily cover up with lies and everyone will believe them;
Combinations of several in any one person.
