Spoilers for Cloche’s Cosmosphere.
Here, the first line’s meaning is mostly lost, because of inaccurate and ungrammatical translation.
When 行動理念 first appears, it’s the completely wrong “the idea I have”. The second time it’s the slightly better, but still incorrect, “philosophy”, but the sense that Cloche is about to reveal the reasons behind her recent behavior is completely lost.
The third time, we get “the reason for your action”. Closer, but so disconnected in its grammar and in meaning that it barely makes sense with the scenes and lines leading up to it.
Finally, the punchline: someone thought that “a wish to destruction” was a perfectly fine translation. “Only if Infel was here” is icing.
