Each profession has it's strengths and drawbacks. Usually you will want one that will complement your class.
For instance, Warriors, Death Knights, Paladins might want to take up blacksmithing because you can make your own armor, and if you take mining with it, you get the bonus strength from mining.
Casters (mage, priest, warlock) will want tailoring to make their armor. grabbing enchanting along with it will be a great money maker and the armor you make with tailoring can be disenchanted into mats needed for enchanting. The spell thread from tailoring can be put on tailors pants at a greatly reduced cost and with enchanting you can enchant your own rings.
Leather wearers (Hunter, Shaman, and Rogue) will want leather working as it can make leather and mail armor and if you take up skinning with it, the crit bonus will help you alot. Leatherworkers can make themselfs fur linings for their bracers and their leg armor enchants can be put on themselves at a greatly reduced cost.
Yes, World of Warcraft is violent - but the violence is not explicit and it not the only thing in the game - there are quests and professions that are not violent.
