I just want to call out that, whatever the facts of this case, pilot heroism is way more common than pilot murder. This is off the top of my head, so don't quote me on the precise details, I'm probably misremembering some things. But a few of my favorite examples:

- British Airways 5390: An incorrect repair causes the windshield of a plane to be blown out mid flight. A pilot is nearly sucked out. The head flight attendant holds onto his legs to keep him in the plane. The copilot and flight attendant think he is dead, but they keep the situation under control and land the plane.

Everyone survives - including the pilot.

- United 232: An engine explodes in the tail of an MD-10. Due to rotten luck and weaknesses in the design, it takes out all three of the redundant hydraulic systems, rendering the control surfaces inoperable.

There's a pilot onboard as a passenger who, it just so happens, has read about similar incidents in other aircraft and trained for this scenario on his own initiative. He joins the other pilots in the cockpit and they figure out how to use the engines to establish rudimentary control.

They crash just short of the runway. 112 people die, but 184 people survive.

- Pinnacle 3701: Two pilots mess around with an empty plane. They take it up to it's operational ceiling. While they're goofing off, they don't realize they're losing momentum. They try to correct too late and cannot land safely.

In their last moments they decide to sacrifice any chance they have to survive by not deploying their landing gear. They choose to glide for the maximum distance to avoid hitting houses, rather than maximizing how much impact is absorbed. They do hit a house but no one else is killed.

Here's another one:

Air Canada 143

- Pilot calculated incorrect fuel due to metric/imperial unit mixup, and ran out of fuel midair.

- Said pilot performed an impossible glider-sideslip maneuver to rapidly bleed airspeed just-in-time for an emergency landing at an abandoned airfield, having to completely rely on eyeballing the approach.

- No fatalties or serious injuries.

It was a series of events and failures rather than simply “pilot calculated incorrect”. And it was a bit more nuanced than metric/imperial conversion.

Via wiki (but accident section is more detailed):

“ The accident was caused by a series of issues, starting with a failed fuel-quantity indicator sensor (FQIS). These had high failure rates in the 767, and the only available replacement was also nonfunctional. The problem was logged, but later, the maintenance crew misunderstood the problem and turned off the backup FQIS. This required the volume of fuel to be manually measured using a dripstick. The navigational computer required the fuel to be entered in kilograms; however, an incorrect conversion from volume to mass was applied, which led the pilots and ground crew to agree that it was carrying enough fuel for the remaining trip. ”

It's not an impossible maneuver. Glider pilots do this all the time especially if they don't have spoilers

I would say it is much much harder. The wing configuration of an aircraft dictates the minimum glide speed. The more angled (for a better word) the wing, the higher the speed it needs to be at to be able to glide and not stall.

Yes. On a plane which is designed to be a good glider. I highly doubt a 767 is designed to be a glider. It's definitely not impossible (after all, it was done successfully!), but certainly a very difficult (and undocumented) one on such a plane.
