Even the Bible said that :

hand join in hand, the wicked shall not go unpunished.

The Queen deserved what she got. She deserved such miserable end.
You know, this gets me thinking and I really wonder why the heart of man is desperately wicked.
Now she's dead, her husband is dead, and the kingdom will depart from her lineage to another, all thanks to her ☹️.

The important lesson here is that we must realize that all our works, both secrete and open will be rewarded, and we'll receive equal measure of our deeds. And before embarking on any selfish ambitious endeavour, think about the short and long term consequences.
