There is a mechanism for allowing humans to progress by carrying over learnings from previous lives.
The theosophical account of this uses "permanent atoms"
For example, a human having refined his/her emotional structure in one life, now needs to build a new emotional structure for this life that retains the work of the previous.
It is said that the human carries over "permanent atoms" that contain the essence of previous achievement to serve as the core for the new emotional body.
Similarly for all the chakras directly connected to the spine. (There are said to be 7 major, 49 secondary and 343 tertiary chakras)
There is also karma of various types. This can be strongly structured.
And of course the light body substance on all the planes is biased by planetary and cosmic karma.
Then too, adverse entities manage families as emotional food sources.
Also some that incarnate as humans coming from outside the solar system, attract spiritual suppression over many lives. I knew a woman who was tempted to suicide every time she drove past a tree, but was quite clear that suicide was no escape. The next life would be just as bad.
Then there are visitor humans that are transparent to their guiding light/purpose.
Living in places with adverse Earth energies certainly changes a human's character.
Parallel existences should accelerate learning
Soul access to the human is greatly restricted by the substance and quality of the brain. Aluminum and lead are major problems
There are many more aspects that influence character including family, education and work.

Situations and events I see as separate from the character. Situational yes, but more in the sense of environment. Not everyone will react to the same scenario in the same way, it depends on their character how they proceed. A character can change but only with what it has endured.
To summarise my proposition: the personality is the dynamic result of a large number of small and large internal intelligences that are learning by experience.
The term character commonly refers to the manifestation of the personality e.g.
"character: distinctive feature or attribute; nature; disposition; makeup"
