Quoting the wise Sage Yoda

Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering. Since darkness is traditionally liked to evil the “Dark side” is so aligned to. And Fear is thus the path to Evil leading to the conclusion that Fear, and being filled by Fear, is aligning, or being aligned to, Evil. So on the Good-Evil axis Fear of Spiders is aligned to Evil. Fear being an emotion have no intrinsic aligned towards Order or Chaos, how it affects the person is individual.

Therefore Fear of Spiders (arachnophobia) is Neutral Evil.

If there are three players present I’ll run. Unless there is something big upcoming, then we’ll discuss if we want to postpone. I usually say “I want four players, so I’ll recruit to five, and run with three”.
