A lot of people hate Musharaff and try their best to come up with different issues to prove that he is a corrupt person, some even say that he is the MOST corrupt leader ever ( even deep down their heart they know it's b** $**t ).
Of course people hate Mush, precisely because he was a corrupt dictator who brought much misery to Pakistan.
The dictator chose the most corrupt politicians in Pakistan as his allies, Sheikh Rashid, Chaudry Shujaat, Altaf Hussain ,etc, and they all lied and looted, leaving Pakistan in the state it is in today.
