Opening a charity hospital is not wrong but using it to serve your evil purpose is wrong.
I've given you examples of great individuals; none of them used their social work for any political ambitions.
It proves that Imran Khan is a fraud who uses other people's money to run his own politics.
His ATM machines also prove him a parasite.
To begin with, IK is not part of SKMH anymore in any capacity other than fund raising, so let's leave that aside. Now let's address your bone on contention that he is using the name of this hospital to advance his political agenda. So why does he occasionally mentions the hospital: here are some of the reasons:
1. To motivate people in believing in themselves. When everyone was convinced that building and running such hospital was impossible; he with the participation of public made that dream a reality. Basically saying that anything is possible if one has a dream, is committed to fulfill it and works relentlessly to achieve it. This is an attribute that any leader is supposed to have.
2. To let people know that if he can build one hospital (now two) from money collected from public; he can build many more institutions if he has access to their money collected through taxes.
3. SKMH has been rated as one of the finest and best managed hospital offering free cancer treatment to 70-75% of the patients. The reason being that there is no political interference in its operation, and all staff are selected based on qualification, merit and rewarded on performance. So if same model is introduced in the government institutions and bureaucracy, a similar performance can be expected.
Anyone can do anything with public funds while in power; that's no brainer. The stealth is when someone achieves heights with inner strength and self motivation despite all odds. He is presenting SKMH as a fruit of his labour, a model of governance and as an achievement for his resume.
