Hi,
This is a hard question, there are a lot of factors to consider. Terminally ill people i believe should be able to end there life if they so wish, but other people, well i have heard of people killing themselves because there boyfriends left them...... this is just a lack of maturity i think. I guess in the end people that really want to end it just will, and those that are seeking attention will just try and end it in the hope that it will make people care (sad really)
At the end of the day you can, there is not much to stop you but i only hope that if people do it they do it for real reasons and not emotional ones (these often reflect on the caring of a society)
The chose is already there and always has been.
(NOTE; i am not religious so i will not comment on any aspect of peoples faith)
Hope this gives you one answer to your question.
