When the girl awoke, she knew that she would bear twins. Even before they were born, there was contention between the twins. There was no peace between these two brothers. When it was time for them to be born, the right-handed twin wanted to be born in the normal way. The left-handed twin saw light in the other direction and was determined to be born through his mother's mouth or nose. In his attempt to be born in the opposite direction, he killed his mother.

Based on this excerpt, it is reasonable to conclude that
the brothers were opposites and would always be in conflict.
the right-handed brother was smarter than the left-handed one.
the left-handed brother wanted to murder his mother.
the two brothers despised and wanted to kill each other.
