why do I like him

Zoro is confident but often acts in a very comical manner. A running gag is that he has a terrible sense of direction (being capable of getting lost even while walking in a straight line) which he is very insecure about since he never admits when he gets lost, instead always blaming someone else. While the crew is out at sea, Zoro can (usually) be found sleeping or training towards his goal of becoming the world's best swordsman. He and Sanji have a great rivalry, often resorting to fighting (both verbally and physically) over issues from minor to extreme. Zoro had never called Sanji by his name in the original Japanese manga, he uses phrases like "dumb-cook", etc. On the other side, Sanji uses phrases like marimo (moss-head). etc. Though not a samurai, he appears to maintain a certain degree of bushido and is frequently mistaken for one. Unlike Luffy and most of the other Straw Hat Pirates, Zoro has been known to kill his opponents if he has to, though never in cold blood. It is shown that Zoro enjoys fighting a strong opponent (usually left to face down the second strongest villain in each arc, as Luffy faces down the strongest). Zoro tends to retain a maniacal grin and serious glare when battling a worthy opponent.
