There are a lot of different ways gas can be bad - high water content, lots of dirt, high varnish content, low octane, other non-burnable content, smoking, drinking, playing the horses. OK, not the last stuff.
A lot of things can go wrong with bad gasoline. Deposits on the valves and seats would be one. Gunked up injectors. Clogged fuel filter. Knock so bad that the fuel system can't adjust for it. Yes, it will result in the lack of performance, and can damage the engine.
Will this particular fuel destroy the engine? Can't say. But cheap gas isn't good stuff, and the downside is a trashed fuel system and a trashed engine. And frankly, by the time you notice a performance hit, it's not good news for the engine. Valve deposits don't go away with a bottle of Techron, and a misfire or knock can chew a hole in a piston.
I don't understand about fuel additives hurting the oil. Gasoline doesn't usually get into the oil. The gas burns before it gets there. Gasoline in the oil will hurt the engine - gasoline is NOT a good lubricant. Additives would be a small percentage of the gasoline (a pint of additive in 15 gallons of gas is all of 0.8%) - if an additive is diluting the oil, you've got a lot of gasoline in the oil, and the only way it gets there is past the rings unburned. You'd notice that.
Additives are not an antidote to bad gasoline. The analogy would be bad food. Not bad food like eating pizza and fried foods all the time - it's like eating pizza with spoiled cheese, dirt, and those funny little things the health department gets all upset about. And toss in some heavy metals for good luck. One meal like that probably won't kill you. If that's all you eat, or if you eat it half the time, you're life expectancy is going to be pretty poor. Now, taking lots of vitamins will not fix the problem.
Putting bad gas into the car is the same as slamming the shifter around, running at 6000 rpm all the time, locking up the brakes whenever possible, and bouncing off curbs on a regular basis. That's abusing the car. I don't know the situation, but whomever owns the car would (or should) take the keys away if they found out this driver was street racing. Whomever owns the car should make the rules.
