Horus losing it?
SPOILERS FOR FEAR TO TREAD!!!!
ok, I have just finished Fear to Tread and I can say I loved it; very entertaining!
I did notice though that Horus is playing his own games and tried to have Sanguinius killed rather than turned, to head off a potential rival.
Basically my question is, is this simple paranoia on the part of Horus or do we think his exposure to Chaos is twisting his judgement even further, because even the Chaos Gods don't want to win outright (based on the Cabal's warnings to Alpharius/Omegon)
