My guess would be pride. They thought they were invincible, high IQ, successful, wealthy, respected and the like.
It’s beyond me how anyone would think that they would not get caught. Perceived superiority leads them to believe they won’t be caught.
Would anyone plan a death knowing that the police would show up at the airport to take them in? DA thought they/she were above the law and that they were on their way to live out of the country.
As it turns out their ‘intelligence’ was lost on their lack of intelligence.
