Reminds me a bit of the actress, Winona Ryder, who was charged with shoplifting.
In her case, and in this case, both people are well paid and have no trouble paying their bills. They both have the money to buy what they shoplifted, easily have enough money. There’s something else going on in their minds; it not like they are stealing food because they are poor and don’t have enough to eat.
His excuse was “He couldn’t be bothered”.
In reality, they steal because they feel they are entitled to the goods. Sticking it to the store is just their revenge for being bothered to have to lower themselves to make a purchase.
The Cowboys were paying him a huge amount of money to not steal things and he couldn’t abide by that.
