The high point of achievement in Mughal architecture
(Indo-Islamic architecture developed by Mughals in 16th century), represents
the Taj Mahal, described as the “teardrop on the cheek of time” by Rabindranath
Tagore. Emperor Shah Jahan built the Taj Mahal entirely of white marble in
memory of his wife Mumtay Mahal. Shah Jahan decorated the building with large
scale-inlaid work of jewels and symmetrical mirror mosque in red sandstone. The
construction took over 22 years and required 22,000 workers and 1,000
elephants, at cost of approximately 32 million rupees. The Taj Mahal now
represents one of the New Seven Wonder of the World.
The watergate story is your answer I think
The feature is the rule of law. Unlike people, legislature cannot be affected by passion and if law rules then everyone is equal in the eyes of law. If a man rules and has absolute power, they can be affected by various things that might make them abuse their power, and law cannot abuse power on its own.
Another way your question could be framed is “why do nations use imperialism on weaker countries?” and the simple answer is there are several motives such as ethnocentric purposes, religion, access to natural resources, expanding power, etc. Specifically people resort to imperialism on weaker countries because they are vulnerable to accept whatever helps the people survive in times of unrest.
