Kira is one of the best villains in JoJo, as well as within the high tier of anime/manga villains in general. From his introduction alone, it becomes clear how he differentiates from past villains in JoJo and Shonen in general. He has no real megalomaniacal plan nor makes himself imposing, instead just wanting to live a quiet life despite his urges for murder due to his hand fetish making that impossible. There are a few things that stick out as questionable about his actions though, such as why did he consider it a good idea to start talking to his "girlfriend" and partially revealing it when he was buying a sandwich despite his secretive nature? Also, for someone wanting to remove all evidence and never raise suspicion, why did he consider it a good idea to keep his fingernails in labelled jars and make meticulous diary entries on them?
He was at his most interesting during his time hiding as Kosaku as he struggled to enact on his urges and showed new sides of himself in how he subconsciously started caring about Shinobu (also, pretty funny how he was Chad enough to technically cuck the real Kosaku without trying), though it's a shame these feelings towards Shinobu never blossomed into something that could act as a character flaw or a source of conflict later down the line.
Overall, Kira is one of the best examples of how to craft a unique villain in anime/manga as well as how to make a small scale villain just as, if not more, threatening than some world dominating supervillain. Despite this, there are a fair few flaws to his actions that he really should've considered, making Patrick Bateman from American Psycho essentially a better version of Kira.
