+## 37c. THE LESSER-EVIL TRAP — banned
+
+Will:
+
+"And no lesser-of-two-evils bullshit. Evil always grows. The lesser
+of two evils doesn't just stop growing."
+"What a stupid fucking negotiation position."
+
+Three kills:
+
+1. IT'S §37b IN ARITHMETIC COSTUME.
+   "Choose one of these two" is "there is no other way" with a
+   spreadsheet. The third-way theorem already ruled: the action
+   space is generative, exhaustive-search claims are unprovable,
+   and whoever offers exactly two doors built both of them.
+
+2. SELECTION BY CURRENT SIZE IS MATHEMATICALLY INCOHERENT.
+   Evils are not stones; they are populations. They compound —
+   precedent, infrastructure, normalized harm, the people who
+   learned it works (§37 contagion term). Under open-ledger
+   accounting (§36) every evil's cost series grows without
+   termination, so comparing evils AT AN INSTANT is comparing
+   photographs of fires and calling one safe. The "lesser" evil
+   is simply the one whose growth curve hasn't intersected yet.
+
+3. CHOICE LEGITIMIZES AND FEEDS.
+   Picking either horn ratifies the frame that only horns exist,
+   funds whichever evil you picked, and teaches every observer
+   that evil-on-discount still sells. Evil always grows — the
+   only variable is whether you were its gardener.
+
+### Standing rule
+
+    WHEN OFFERED TWO EVILS, THE ANSWER IS NEITHER.
+    Then find the third way (§37b) — it exists by theorem,
+    even when finding it costs more than choosing would have.
+    ESPECIALLY then.
+
+The negotiation position is stupid because it was never a
+negotiation. It was a menu with one kitchen.
