..if you are so unhappy/depressed that you want to end your life then technically it is selfish as I think you are only capable of thinking about yourself and how desperate you feel..but I don't think it's the right of others to judge you for that..
...but I guess if it's a close relative or someone you love dearly then you may feel that perhaps the person could have sought help/medication etc and that it's possible it could have been prevented..there must be a huge sense of guilt too that you were unaware of how unhappy or desperate they were
