A quick read of a few of those and its clear that not all of them even support support your claims, maybe you should read them yourself rather than just reading the titles.
I don't deny that in a small portion of the population these issues exist, but as most of these articles you link show it is an absolute miniscule % and none of these claim more than a probable relationship. NONE find a relationship between suicidality and finasteride. You also fail to consider the fact that depression, fatigue and libido or erectile dysfunction issues cannot automatically be directly linked to use of finasteride. Hairloss itself can generate depression and thereby fatigue or lidibo issue symptoms.
For example in one of the suicide and depression studies
"The absolute increases in the event rates for these 2 outcomes were 17 per 100 000 patient-years and 237 per 100 000 patient-years, respectively."
Quite frankly this is trivial, and if you're using it as an argument to not even experiment with finasteride at perhaps a low dose or in the short term to see if sides occur, you're a moron.
A few of these studies you linked say absolutely nothing at all with no figures or statistics so they weren't even worth linking and you clearly only did so because of their titles. The neuroactive steroid ones findings doesn't have a conclusion on the actual effects of this. Again a waste of a link.
If it's a matter of a few % chance of side effects on the drug and potentially 1/1000 for sides remaining after coming off, that is in my opinion a chance worth taking for most people. A few of those linked studies also assert that the problems actually DECREASE after prolonged usage of the drug, which again could infer links between hairloss itself and perhaps the reduction of it with depression, libido and fatigue symptoms.
Your understanding of "science" is throwing studies with titles that imply your argument has grounding without bothering to read them and properly interpret them. These also don't form the conclusion that finasteride should be avoided. They are ALL talking about occurrences of strong side effects in the range of a few %, which again only someone with no scientific understanding would infer that finasteride is purely to blame.
