Thank you for your answers.
It's been exciting reading.
However, it is a little disturbing to hear that there are a few pilots who do not have a limit, to how many number of defects to be in an operational aircraft.
Even if MEL says OK for each defect.
(just to provoke a bit)

Do pilots and technicians nothing to stop this at some point, then you accept more and more defects, so in the end it is legal to fly IFR only on the fuel gauge.
No matter what you call it, I would call it a defect, for there is something that does not work 100%
Next time I will fly, I will enjoy the trip as always.
I love to fly.

So I let the professionals to do their work.
I trust in your decisions, from mechanic to pilot.
