I don't know whether to choose to use past simple or present simple after when(where).
For example:
I like the part where he kills the villain.
I like the part where he killed the villain.
1 and 2 both sound natural and seem interchangeable.
I like the part where he doesn't kill the villain.
I like the part where he didn't kill the villain.
According to the first 2 examples, 3 and 4 should have no difference but 4 sounds unnatural.
So the question is what is the difference between using past simple or present simple after when(where) in these cases and if 4 has a different meaning, then what is it?
Also
- I like the part where he had killed the villain.
What is the difference between 5 and the other 4?
Thanks in advance.
