Wow, the guy takes over 15 months to do contracted work that could have taken 8 weeks at most?
Seems to me the wrong person got whacked in the head with a hammer.
Isn't there a scripture about "letting your yes mean yes", as in "you entered this agreement, you'd better keep your word"?
This behaviour actually reminds me of the Canadian case of Basil Borutski, who murdered three women in rural Ontario in 2015. He would ingratiate himself to these single women, doing odd jobs around their homes that they didn't want to have done, trying to take over their spare time, etc. really creepy.
He died in prison earlier this month, maintaining his innocence and blaming the women for their brutal murders at his hands. At least he never had an opportunity to go before the parole board or being released after 25 measly years for his crimes.
