Let me tell you what's gonna happen next and in S6 - Damon
sacrificed himself for Stefan which leads to the whole Damon freaking
redemption road I wish I care; Elena will be whining & trying to bring him
back like she did with Stefan in S3, only this time people actually want her to
go to hell to join Damon! Stefan and…

Haha, reminded me what's piece of junk Elena had invited to her bed willingly and happily for months. She's incredible isn't she? This "Bed first talk later" makes her deserve all the crappy titles out there in the world.

They won't let Delena die till the very very last ep of the show; they let die of the real epic-ness but keep dragging out the grossness. TVD writers have alien minds. I even lost interest to read review/recaps, I am only interested in the show's rating.

I would say - ALL of the above you have mentioned. That's why she's one of the most hated lead lady on any TV show right now.

Sinning without feeling guilty because of numb conscious, if that's what your call being free and exciting, you should be sucked into the place where Katherine Pierce went. What TVD seriously lack is JUDGEMENT/Pay day!
