Svid's Suicide and Human Despair

In Part VI, Chapter VI, of Crime and Punishment, Svid traps Dunya in a room with him. From the look on his face we can easily tell that his intentions are less than pure. He has had an unhealthy, infatuated obsession with girl for the past year or so. All he wants to do is get married to ger, but she wants nothing to do with him.
So while she is in the room with him, she gets trapped in a corner. Then she pulls out a three-barrell revolver on him. She shoots at him one time, but it merely grazes his temple and hits the wall behind him. Then she takes a second shot, which completely misses him all together. There is one more cap left in the revolver, but she just throws the gun away from herself, she tosses it across the room. She gives up essentially.
So, Svid takes this opportunity and approaches Dunya. He asks her with all of his heart if she loves him, or will ever love him. Her answer is an absolute no. This sends Svid into a state of despair. So he just gives her the key to the door, turns his back, and tells her to ga away quickly. She does this with no arguement. He then picks up the gun, ans stoes it in his pocket.
Svid gets a cab and goes to a shabby hotel that night. It storms and has he some very bizarre nightmares. He wakes up very early the next day, and he feels resolute, but slightly depressed. He proceeds to a watch tower and talks to the guard there. He tell the guard that he is going to America. Then he pulls out his revolver. The guard tells him that this is not the place for jokes. Svid then puts the revolver to his temple, and pulls the trigger, thus ending his life.
Svid took his own life because of the pain that he was suffering from. He can't get over the fact that Dunya will never be his. So in order to end his pain, he puts himself out of his misery. He let depression and despair get the best of him. He saw no hope, and when humans see no hope in thier lives, they want their lives to be over with.
Despair and Depression are horrible things. If there is no Hope in life, then no one wants to live any longer. If one faces either Despair of Depression, then one must find hope in one's life, or the desire to end one's life will be unbearably strong. Hope is the key to victory over Depression and Despair. It is essential in order to survive.
