Wow, that's some serious Clinton hating there.
I agree that I think somebody that is given a huge opportunity to be the next POTUS by their party should either reject the opportunity or work to the best of their ability to win the election. Unfortunately for the US, Clinton prioritized many things ahead of doing the best she could to win the election driven by her greed and he dependence on the advice of her well trained sycophant team.
Perhaps Clinton's email miscues can be attributed to staggering ignorance on her part, a failure to get and follow the advice of informed individuals and a bit of world class hypocrisy given her blasting of the Republicans for doing the same thing less that a year earlier. So I guess this falls short of intentionally trading off the chances of a victory for self serving reasons.
But for that one needs to look no farther than the wall street speeches. Secret speeches to a group of people that's unscrupulous behavior had savaged the American economy and brought it closer to collapse than at any time since 1929. Or maybe the $250K that she decided to pay herself from her campaign funds. Did she think that was going to improve her campaign chances?
And of course, there was the foundation. She decided that she didn't need to comply with her agreement to isolate herself from the foundation while she was SoS and then she thought it was just peachy for the foundation to keep receiving foreign donations while it was likely that she was going to be the next POTUS.
Gawd! Now Clinton is responsible for Trump?

I suppose it's off topic to point out to you all the racism and sexism that is actually responsible for Trump so I'll defer that to a different thread.
Almost all the theories put forth as to why Clinton lost are right She lost by a minuscule number of voters in a few key states. So if you want to blame racism, lust for authoritarianism, right wing nut job theories, etc. you are right. I put Clinton at the top of the list of things to blame because most of those things existed before the election. It was Clinton's largely intentional self serving actions that were enough by themselves to make up the difference for her loss.
There is another scenario here that doesn't involve anything sinister. It's too bad people are so convinced of Clinton's evil they don't even consider it. To wit, the erased emails, as confirmed today by Comey, were all from her first 3 months and from her Blackberry, a device she switched from. Those are the missing emails.
Comey noted they found some of those on Weiner's computer and guess what, there was nothing in them.

I am not sure that I follow you here. The erased emails that I am aware of were the emails that Clinton claimed were entirely personal and that a very thorough procedure had been executed to insure that.
There were two problems with this claim:
1. It was a lie. A very cursory procedure had been used to sort official emails from private. Any mistakes by her crack sorting team would make it clear that Clinton had lied about this.
2. By destroying her "personal" emails Clinton almost guaranteed a drawn out scandal as new problematic email surfaced when her "personal" emails were obtained from other sources.
An informed 12 year old could have told Clinton about the problems with the way she handled the email scandal. Instead, she depended on the advice of sycophants that relentlessly gave her the advice she wanted to hear. And now she depends on the advice of sycophants to figure out how to blame everybody else but herself for her loss(excluding her self serving, perfunctory announcements of personal responsibility).
