The 'richer lands' were slaughter pens that his army set up, after they had been disarmed. They were slaughtered by the thousands.
Sounds like a genocide to me. Galba profited from the bounty. The Romans had to constantly put out the guerilla forces of the remaining Lusitanians for years afterwards.
Don't trust me? Look at 'Chronicles of the Roman Republic'.
Anyway, genocide was used to gain quick profit, and long-term benefits if you were able to wipe the entire population out. However, with modern society, a genocide isn't called for, and thus society has looked down upon it.
My 2 cents.
