I killed my dad because I wanna be a slacker?
Come on, DM was a busy guy, I think the only reason he would have stepped up and killed WM is if he perceived a problem with the business (MRO) and feared losing their fortune because of it.
He has semaphored this fact to us by stating his interest in Accounting on Facebook and by telling the TS, the thing on the top of his mind when LE came looking for him re: TB was the hangar's accounts

What kind of problem gets DM out of bed early? Financial problems due to the MRO.
Everybody calls him a do nothing but between the chop shop, the MRO, the real estate deals, whatever hangar based business they had in there taking deliveries, etc. he was a busy guy.
DM bought construction materials like faucets on eBay and I think this shows he had an interest in sprucing places up in order to flip them, and wasn't just sitting around waiting for things to happen to him.
If the MRO had been left to run and gain clients, DM would not be running around in his Nazi SS suit in order to run it. I would say the MRO was dress code casual and DM had no fear of having to show up in a monkey suit every day.
Judging by all the crap he purchased that is now for sale, WM did not keep a tight leash on DM. That's why it is unbelievable that DM felt so controlled by WM that he would kill him just for that.
There had to be a financial problem at hand, where WM and DM differed in their concepts of how to solve it.
