I don't like alignment because its an oversimplification of human (or sapient) behavior.

In my opinion, alignements
can be an interesting tool when use as a general guidelines. To give an idea of a character's tendencies.
However, if implemented in a video game, this could turn "general guidelines" to rules and it could prove way more restrictive than helpful.
I like to have characters that (like real life people) are more complex than "I'm this alignement" or "I'm this alignement and maybe one day it would be another one".
When doing "alignement test" multiple times (on different days or websites), I know that people (including me) don't always have the same results and don't necessarily have "black and white" or "100% you're this" results.
I like to have characters that work the same way.
Something to note, often we all don't even agree with the definition of the different alignements or disagree on their interpretation (this thread alone contains proof of that). Making it extra difficult to implement, especially in a way that's satisfying to most.
Like others here, I like the idea of
actions having consequences more than an alignement system.
