You should learn to have more faith in humankind and the resolute of favoring an end to suffering. This, for those who are at this stage do not decide to end their life, they decided they themselves would not like the world anymore. It is something that can not be helped or halted once in motion. As for the game, I had my best ending when the MC chose to honor the memories , maybe give it another shot.
Not sure what you're trying to say with your first sentence, but no, suicidal thoughts isn't something that "can't be halted once in motion", that's a very dangerous suicide myth. Suicidal thoughts don't have to result in an actual suicide, and people with such thoughts can be talked out of them, or not work up the nerve to actually kill themselves, particularly if you make it harder for them (putting up fences on bridges, for example). Myths like that suicidal people will kill themselves regardless make it harder for people to reach out to people with such thoughts.
I hate to be put in the position of the one arguing against all the good things you said, but I must. Maybe we have different experiences with such a personal matter and it has brought us to 180 in direction. My few experiences with suicide have been hard and real. The one common demoninator from both was that nothing was going to prevent them from happening. When someone has reached the end of the line in what they feel is enough pain, physical or mental, the only thing a person does when they interfere is add to the already agonizing predictament that the person is in. I will gladly give heed to NOT all suicides are this way nor do all suicide attempts want to die. But it is no myth, that there are some people in this world that for their own reasons they do not wish to endure or can not endure any longer, this is what I meant by my first sentence to the readers and you. It is not always best to get involved with a person whose mind is made up to end their existance and can often, not rarely, but often lead to a more dangerous or deadly road then the good samiritan is preparred to handle. Sometimes you must trust in humankinds self preservation that is in us all and step aside and let what will be done be done. As crazy as it may sound to you or someone like you, that is a selfish thing to inject your opinion onto one who has gone through it all and came to this conclusion. Afterall it is why there is now clinics that assist those who have made up their mind to die. The ones I have personal connection to felt what they were doing was right and only peace and fullfillment awaited them upon completion. There was no words or person who could do anything but harm them more by interfering. Thank you for replying back and sharring your mental picture of where you get your actions from. I hope you accept my reply in the same manner of respect as it is sent with no ill intentions towards you at all. I would like to just add this one part, I did not indulge on what or whom I had experience with. With that being said, good and evil walk hand and hand down the road of life. Not always clearly defined which is which, until they come to a fork. Iti s at that fork that we must all make the decision on which way to go, and some can not make the right call for all the evil they may have brought onto others during their journey so far. If you encounter this person, hug them and let them go otherwise they may blame you for their actions afterwards, not be thankful for your stopping what they should have been able to do. That is no myth either, but true hate for the one who interfered. From me to you, keep on living and hopefully just by you living it will keep some alive without any action by you.
