Weird news - Pilots shut down wrong engine

The safety of an aircraft when it is flying is controlled through a series of checklists and procedures, and if pilots deviate from that, it can have deadly consequences. These procedures also typically handle what to do when the plane goes through some disaster, such as a storm or lightning strike, or a bird hit. Normally you would not expect a bird hit to impact a plane significantly, but the plane moves at very high speed, and because of the speed, a bird hit on the engine can significantly damage the engine and cause fire in the engine or it to shut down.
So, if a bird hit happens on the engine, depending on the severity of the strike, the pilots may shut down the engine. There are multiple engines on a plane, so the plane can still work on the other engine(s); however, what happens if a bird strike happens and the pilots shut down the working engine by mistake and leave the bird hit engine on. It can become very critical, threatening the passengers, and the capability of the pilots can be questioned (link to article):
The pilots of a GoAir flight going from Delhi to Mumbai shut down the wrong engine after a bird-strike incident on June 21, 2017, the aviation regulator Directorate General of Civil Aviation (DGCA) said in a report. While engine number 2 of the flight was affected due to the bird-strike, the pilots of the GoAir plane decided to shut down engine number 1, the report said. Once the aircraft stopped climbing at an altitude of 3,330 feet, the pilots "realised their mistake", and consequently started engine 1 and brought back the plane to Delhi airport, said the report dated November 5, 2018. "(The) incident was caused by incorrect identification of engine affected with high vibration followed by non-adherence to recommended procedures, lack of situational awareness, poor cockpit resource management and poor handling of aircraft during emergency subsequent to bird strike," it said.
