Ideas:
1) Huge grant for really unethical project (hint: don't try it on this forum, don't lead us to temptation ;) )
2) Let masses forbid her reasonable pet project because of some phobia (like nowadays is being treated GMO or nuclear power). (not only revenge, one may also doubt the whole system as such...)
3) Snowballed... Did not really wanted much at start, just when some conflict were starting were winning them, and each victory was making her stronger but with more enemies, what was leading to arms race and preemtive strikes.
4) Problem with being too rational. Is shooting one innocent guy by over eager police a fair price to have more effective police and save two people from being murdered? If you say "yes", then you:
-just trashed all official ideology that we're expected to believe;
-technically speaking gave an answer which is in accordance with economic theories;
-justified having a police state.
