Okay, but none of that precludes "introducing thought" or planning in one's self interest. A high-Int/Wis Chaotic still has a functioning brain.
Sure it does.
"By promoting chaos and evil, those of this alignment hope to bring themselves to positions of power, glory, and prestige in a system
ruled by individual caprice and their own whims."
There's no thought behind caprice and whim.
Here's the 5e version.
"Chaotic evil (CE) creatures
act with arbitrary violence, spurred by their greed, hatred, or bloodlust."
Acting arbitrarily is acting without thought.
2e: "These characters are the bane of all that is good and organized. Chaotic evil characters are motivated by the desire for personal gain and pleasure. They see absolutely nothing wrong with taking whatever they want by whatever means possible. Laws and governments are the tools of weaklings unable to fend for themselves. The strong have the right to take what they want, and the weak are there to be exploited."
Might makes right. Take whatever by whatever means possible.
3e: "A chaotic evil character
does whatever his greed, hatred, and lust for destruction drive him to do. He is hot-tempered, vicious, arbitrarily violent, and unpredictable. If he is simply out for whatever he can get, he is ruthless and brutal."
Might makes right. Driven by his emotions, not thought.
4e mucked with alignments a bit and I didn't play it, so I don't know what it said. For the rest, it's all about caprice, being driven by emotion, and whim. Rational thought is not really involved. The only thing that's going to rein you in will be knowing that someone or several someones are out there to stop you, and then only if you think they can catch you.
