His gambling was nothing new, he had been doing it for years. Killing Joey and his family would just cut off that source of income to gamble IMO
How would he be able to do that other than stealing from Joey?
He was already getting less pay from Joey, and was no longer involved in the big money making part, which would've been welding, and not the catch all jobs he was then doing?
And then he began writing himself fraudulent checks from that same business owner's account?
Do you truly believe Joey was going to let that slide? Stealing from the very man who had helped him out, when IMOO, others wouldnt have spit on CM if he was on fire?
You really think that would be okie dokie with Joey, and no big deal for him or Summer? Biting the very hand that had fed him for so long. when no one else did?
Do you truly believe Missy that wouldn't have been a big deal? Loaning money is one thing, but stealing money isn't even comparable.
As an aside. You seem so convinced that CM deserved to get the money he was paid for the P project.
Do you think Joey deserved to be paid for every dime he had loaned CM to pay his gambling debts?
Do you think CM should have manned up, and repaid Joey for supporting CMs partner, and his three children everytime he went back to jail?
Imo, no CM wouldn't have been better off with Joey alive. He knew his days were numbered working for Joey, already by phasing him out on doing the big money making part of it, when cutoff from doing any of the welding any more.
He knew if he had to stand on his own again on his own credit rating, not a dime in his pocket, and sole reputation as a self employed business owner, he wouldn't even have money to buy cereal to eat much less gamble.
And it was no one's fault but CMs alone . He was not going to be working for Joey anymore, and he knew WHY.
He had finally done something so egregious to his cash cow, even the cow was fedup, and was going to kick his worthless butt to the curb. CM didnt know when to quit stop being a lowlife thief. Imo it was in his blood to take from others. It was never enough.
He knew he would have to do just what he did, after scamming, and, murdering Joey, and go on to conning other business owners out of thousands, which is exactly what he did.
He knew he was one phone call away from going back to prison.
No way, no how was Joey or Summer going to tolerate him stealing after already owing Joey thousands.
If you dont think Joey would have done a thing about it, surely you will admit Summer wouldnt have tolerated CM stealing for a nano second.
She already knew what a blood sucking leech he was, and how much he was costing them just by having him as a sub.
Imo, he had multiple motives to murder this family, including hiding his dirty secret that he was stealing from the family he had murdered, hoping to silence his illegal dealings from coming to light.
