Not all consequences are foreseen nor desired.
All action is impelled by desire.
If an action to be taken is known to not satisfy the desire, why act out.
If an action will satisfy the desire, action may be taken to satisfy the desire. Success is not guaranteed.
Desire clouds wisdom and the unintended and unwanted results ruin our best made plans.
Satisfaction achieved fails to last.
New desires grab us, ever more and more driving desires deluge and delude the dull.

Some karmic-comeuppance is quite entertaining to watch when one is sitting outside of those dubious desires.
