Helena is a dick at the beginning of the game all due to her own domestic solicitude that still got plenty of people killed.
Seeing as how Helena only cared about getting to the cathedral at first, left her post, got tons of people infected and Leon mostly ran into the fray to save all the people he could you couldn't be anymore wrong with this post so I fixed it for you.
No fanboying here just strictly gathering what I realized from the plot and dialogue. If Leon was a dick he would have every right to be one due to all the crap Helena caused I'm surprised he didn't lose his s*** when she told him she aided Derek but they always project problems on the antagonist in a typical manner.
*The Last Of Us Spoilers Below*
I will agree with one thing that is why I like The Last Of Us so much in terms of story because the protagonist causes a bunch of crap to happen by killing people before the winter chapter so they get in deep trouble for their actions once Ellie gets captured by David. He's still a sick SOB but that's part of the realism. Actions have can have consequences and everything happens for a reason.
