UNPRODUCTIVE SUICIDE ATTEMPTS or why the word PRACTISED is not the case of Lubitzs earlier actions Very often people who intend to commit suicide have had many interrupted attempts to do it when suicidal impulse is not strong enough to overcome natural fear and resistance of rational thought For example people trying to commit suicide with a gun often put the weapon to their head and then they interrupt this action moments before they pull the trigger Viewed from the side those unsuccessful suicide attempts are like theatrical act but this is just an illusion because every such attempt has the potential to end tragically In the case of Lubitz  in the situation in which he intended to carry out his suicide there are several circumstances that limit his freedom of choice to interrupt the suicidal attempt  such as returning of the Captain or what you are doing in the cabin These circumstances can force his unproductive suicide attempts to became productive one in any moment and he knows that after them he will have no choice to turn back For this reason it is normal he to do first timid attempts  which were unsuccessful in the first flight Duesseldorf to Barcelona because time is not limited On his return back Barcelona to Duesseldorf the end destination is forcing him As I said he has not PRACTISED but was TRYING to commit suicide or in other words  he had unproductive suicide attempt
