How did MF even make it to the end let alone win Bigg Boss 17??

After the boring start, Munna had where he kept on talking and talking but wasn't really saying much. Then Ayesha came and showed us the true colors of Munna but that did not stop him from becoming a serial BS-tter! It was a chain of disastrous failed attempts to regain his fake persona of a nice guy. So first he did not have a spine, then he lost his credibility when his fake image was blown over, then allegations of cheating on multiple women at the same time and abandoning his own kid and wife. How can anyone recover from that let alone win the show? Also how can anyone support such a vile human being that can fall to any level just for his profit? I just don't get it. Please fill me in.
