Usually of what I seen in the media the creators script writers etc are so full of themselves when the do a fuck up they don't tend to admit their faults and just double down. Truth to be told I seen also smaller writers tend to sometimes do the same ego trip and make fools of themselves.
I think they're trying to convey how often Poe has been through this, and that he's "tuff". People react to server loss or stress in weird ways. Once knew a guy who, when he was tortured, used to have uncontrollable fits of laughter. Weirdest reaction to physical pain ever.
Cooleo. So why lash out emotionally and get himself captured? The scene contradicts itself so that kylo ren can do a cool force move and they can set up poe meeting finn.
As someone who went trough personal tragedy and loses well I would say his reactions don't make any sense. Absolute devotion to revenge his friends death no matter the cost or dedicating to the mission and trying to run away in an epic starfighter chase would be more preferable. Example lets make the scene epic for like> he goes to his x wing after taking some TIEs showing his skills as an ace pilot. Then he tries to surprise strike Kylo only for this one to use the force to crash land his x wing and get captured. Injured he is captured etc etc.
Of course there is a possibility of someone acting like this... But first you establish that - or - if this is suppose to establish that he is mentally insane, keep that in the show and let him be a insane sociopath. And let's not even get into how many more problem that creates.
