Steal – to take without permission.
Steel – an alloy of iron. Also, to harden one's emotions in preparation for an unpleasant event.
Stele – a commemorative marker, usually taller than it is wide.
So, basically, if you steal the king's flowers, you might have to steel yourself for the possibility of having a sharp piece of steel separate your body from your head. But if it makes you feel any better, maybe someone will erect a stele to remember you by.
