First, the phrasing is a little hard to figure out, as "right" and "motive" are not synonymous, and neither are "commit" and "attempt". In the latter two, it's more understandable to some extent? But anyways, not to go too into detail, I'm being led to cherrypick my ways of answering this question. I'll answer it in whatever way seems to make most sense.
"In your opinion, do you think the motive to commit suicide is debatable or not?" - The motive? Generally speaking, many people can and would debate anyone's motive, so yes, it's technically debatable,...
...but would I debate someone's motive to kill themselves? I can only say it depends on the motive, but within my own conclusions, i'd recommend against suicide.
In my case, I felt little reason to continue living, as I resided within an existentially nihilistic worldview. I avoided that by somehow coming across the thought that when regarding our existence, if life seemed pointless, death would be equally as pointless. Everyone's case varies though and may depend on misfortune in their life, or on having the knowledge of the misfortune of others, or on any other sort of perspective or basis.
Hopefully it sufficiently answered the question.
