First of all only one episode of legends has aired so you can't even use that as an example. That being said, the pruducers already confirmed she will be dealing with her bloodlust anyway. Being able to control your bloodlust isn't the same thing as not having any bloodlust. The rules of time travel are inconsistent and vague though so i'll give you that.

And no.Thea never died. If she died her soul would've left her body plain and simple. A person's soul does not leave their body unless they die which is why Sara was a mindless creature when she was revived and Thea wasn't. Also this is taken straight from the wiki

The Lazarus Pit has the ability to delay a person's aging, allowing them to retain their health, physical prowess, and youthful appearance throughout this usage and likewise enables them to extend their lifespan at least for hundreds of years. The water also is able to instantaneously heal all the user's previous wounds with no lingering signs; to which it can also restore one who is close to death. The waters can even resurrect the dead, but only the body, while the soul stays apart from the body. This leaves the resurrected person a mindlessly aggressive animal, prone to violence and killing,  the Lazarus Pit contains traces of the souls of every person who has ever bathed in its waters. Those revived near or from death become so consumed by these negative effects that they become bloodthirsty once excited in battle.

Everything else you said I can see where you're coming from. However, I don't think Thea overcome here bloodlust, since the only way to get rid of it is by killing Rah's. That's why i think she'll sacrifice herself to stop Dahrk out of guilt and because his powers don't work on her
