Bitcoin ATMs are known for their high prices, like they sell far above what Bitcoin is being sold for in the open market, so if they can pull that up by implementing that in all their stores, then it's obvious that profit is what they will make exactly.

I have not read stories of Bitcoin ATMs being hijacked. How exactly will they benefit from doing that since the machine is not like a cash ATM where things are stored inside unless they will somehow tamper with the program in order to steal from the machine without making an actual payment, or is their target the cash buyers who use it to buy bitcoin?
