I don't blame anyone in particular, but I would say that I am disappointed in society as a whole, the general attitude towards suicidal people and treating them like criminals, diseased lepers, or some plague. Most suicidal people just want to end their pain and misery, yet they are being denied the option to do so humanely and peacefully, with dignity. Some of them do violent things and hurt others (which I don't condone or excuse) while others go about it in gruesome ways (firearms, hanging, immolation, jumping from height, jumping into a busy traffic, etc.), sometimes inconveniencing others and even traumatizing them.
So on short, I don't blame anyone specifically, but rather collectively at humanity itself and it's general selfishness as well as it's anti-choice, anti-suicide sentiments.
