Shia folks all around the globe

Await the 12th, the harbinger of hope

He reappears, correcting the mis...

Takes away all the wrong souls


some elaboration on the 3rd and 4th vesrse

In this case, dividing "mistakes" creates a sense of anticipation and suspense, leaving the reader to wonder what the "mis..." refers to until the next line reveals the full word. This technique which is called "enjambment" can be used to emphasize the importance of the word "mistakes" and draw attention to its meaning within the poem

Here are some additional reasons why your interpretation is strong

It fits the meter: The poem seems to have a consistent meter, and adding "takes" at the beginning of the fourth line would maintain that meter

It's a common poetic device: As mentioned before, enjambment is a frequently used technique in poetry, and it wouldn't be unusual for the poet to employ it here

It makes thematic sense: The poem seems to be about correcting wrongs or injustices, and "mistakes" aligns with that theme
