leap of faith or suicide?

Inception is an amazing movie. i just love the meta-physical and philosophical flight that it gives me. the end, the leap of faith sequence between Saito and Cobb is the pinnacle for me. watch it on youtube.
Why did Cobb ask Saito to take a leap of faith, whereas he could have also asked him to commit suicide? the actions would have looked similar to the eye. so what changes? got me thinking.
what is common?
- both have the fear of unknown, what next if i do this?
- both are seeded by a thought that originates in one’s mind.
- both have some external stimuli. by external, i mean external to the mind.
what is different?
- the thought that triggers suicide has to do with giving-up and wanting to bring things to an end. negative. whereas, the only motivation behind taking a leap of faith should be to overcome the fear of the unknown within. positive.
- for suicide, i don’t blame external stimuli as much as i blame the weakness of the mind. only a weak mind can lead to an action as stupid as suicide. negative. in the other case, the external stimuli, be it a person, or reading, helping one take a leap of faith has to be someone they trust. positive.
wait this got me thinking deeper. now this is the tricky part.

one may think they trust the person or reading, but there is a possibility that they are not worthy of trust. that is where experiences count, because, trust is inspired from experiences: what kind of change has prior experience with that person inspired in oneself? having followed that person or reading, what has been the outcome - pleasure or pain?
it’s great if one gets this right. they succeed and enter into a new realm (i remember super mario here). good. but one may misinterpret the experiences, or misattribute (this is even more dangerous **) the good in those experiences, to that person or reading who didn’t deserve it. one may be convinced about taking a leap of faith and end up committing suicide.
needless to say, if you apply consequential morality, only the final outcome of a leap of faith or a suicide can decide which one of it was performed. one better be on the happier side :)
** if you don’t know misattribution you must watch this lecture starting at the 44th minute.
