Imperative form of 分かる
There’s nothing really special here but it’s kinda unusual. 分かる is a verb that behaves the same as a potential verb. Meaning that 分かる is not a volitional action, but it’s rather a state someone is in that cannot be controlled.
For this reason, using the imperative form can come across as a bit odd logically. It’s kinda hard to tell someone to “become able to do X” as an order, however for 分かる it kinda works in the right context.
Here’s a couple of examples:
The first sentence, in the context, is a character frustrated that no one understands him and he’s lashing out by saying “understand me! understand me!”.
The second picture is using the common grammar
<imperative>と言う which means to tell someone to do something. In this case he’s complaining that he’s being told to (try to) understand the pain of others by someone else.
