EMBRACING LIFE OR DEATH?

What’s the difference between suicide, martyrdom and the urge to live? Could suicide and martyrdom be one in the same? Could those 2 ideas go parallel in an event, decision or reason?
I saw a movie just the other day, about a man who turned crippled after an accidental dive in the ocean. The man was used to living as a traveler, a man of many adventures and earthly experiences! His life after the accident wouldn’t be the same again, he would be incapable of doing all those things which he enjoyed so much; his life was now empty. Daily in our lives we get existential crisis, where we question our whole being, why we are who we are, why we choose what we do: existentialism basically describes an idea that one is responsible for his or her own actions, one is because of one said so. The human mind works as, if you don’t like something you get mad about it, if you question something in yourself that is very important like your life or reason to be, you are meant to sink in emotionally. Depression can come from asking yourself those sorts of questions; by your lifestyle getting deteriorated because of an action you committed (whether on purpose or not) you are bound to detest that event, that reason, that decision and mostly the person you are now. The crippled man from the movie loathed himself and his new lifestyle, he thought that everything in him was useless and so why would he have to keep on living and just cramping and using up “valuable” space in this world if he can’t incorporate anything good to it anymore. If he decided to die, whether by killing himself or approving to be killed, would he be committing the sin of suicide or would he be courageously saving himself, his loved ones and the world by becoming a symbol for a martyr? Truth is, I disagree with this action or decision being called suicide, it should be in your own head whether you want to live or die. I don’t want to sound pessimistic by saying that the man would probably be right and his life would be useless, but in my opinion it probably wouldn’t and it would be a braver action to decide to die rather than live as a vegetable each day remembering what you were. By this man be willing to get killed (not kill himself) he would at some level be accepting his role as a martyr, but at some parallel echelon he would also be committing suicide. The difference of these two would be that, martyrdom be classified by himself as freeing yourself from a self pain and liberating your family of seeing you lifelessly in a bed, and suicide in contrast, would mean that everyone else judge your decision and still be hurt because you decided to give up and leave them behind. My judgment and conclusion in all this, is that both opinions are valid in the way that they both use a selfish or self involved judging rather than an actual care for either side: the family feeling ashamed or let down by the man, should actually be feeling alright or at least relief that he did what he wanted and not be in pain anymore, while the man by deciding upon dying voluntarily is in his own right, he is also acting selfish because he is thinking about himself and his own pain rather than his family’s.
Perhaps what it normally comes down to is the genuine human nature of your life, your heart and decisions: martyrs don’t exist if they are originally selfish, and suicide is impossible if you think one has the right to decide his/her future. Maybe the decision to live or accept death shouldn’t be questioned at all and hope to leave it to fate.
