>light behaved like the typical 4chan user
Not really. For one, he was tall, handsome, charismatic, intelligent and popular, all of which goes against the 4chan stereotype
>he killed lind taylor for no reason
It wasn't exactly for no reason, since he wanted to prove that "Kira" was real and could fuck up anyone that challenged him, but yes, even Light admitted this was a mistake and learnt from it.
>he killed ray penber for no reason
Light believed - incorrectly - that Penber and the FBI were onto him and about to close in on him, and he panicked and wanted to get rid of them. He didn't realise that Penber didn't actually suspect him. But Light was actually justified in being paranoid because their suspicion of him is exactly what motivated Naomi to suspect him. We know that they were about to clear Light, but there is absolutely no way Light could have known that, and from his perrspective it seemed like they were closing in on him so he had to act.
>the author had to kill naomi misora to save light
Yes but Light could have killed her easily if he wanted, but accepting the shinigami eyes deal. It's actually to Light's credit that he finds out a way to kill her without doing that, easily one of his most clever and devious moments.
>If it weren't for ren, L would have caught him.
Well, yes, but again, it was Light's scheming that helped him win. He took advantage of Rem to win because he accurately predicted what Rem would do in a very specific situation he manufactured. That's what Light is so good at - taking advantage of people by using his charisma and people skills to fuck them over.
