In the above post, I was mainly referring assisted suicide in the cases of old age/terminal illness.
However, in the case of young, healthy people committing suicide due to depression/breakup of relationships etc, it is a different situation. In such cases, they may generate hateful/angry thoughts towards others or themselves and that is bad for them. They are not only terminating this life, but could be also terminating what is left of their human bhava.
Therefore, in such cases, Johnny’s reasoning is valid.
