Making sense of "心配させる" (causative verbs)

Question

I'm trying to understand the phrase 「Ａを心配させるな」 by "sounding it out" in English.

I can understand 「Ａを心配かけるな」as meaning "Do NOT associate/connect any worries with Ａ!!!". In my thinking, that makes sense.

But, I can't think of how to "sound-out" the phrase 「Ａを心配させるな」 into English. As 「させる」 is causative, the command would seem to have to be directed at the person who is causing someone else to worry: 「田中さん、Ａについて、Bobを心配させるな。」 "Tanaka-san, do not cause Bob to worry about A." And, "Bob" is the one who is worried, and "Tanaka-san" is to whom I am giving a command.

Yet, this discussion asserts that 「Ａを心配かける」and 「Ａを心配させる」 have the same basic meaning, at least in some situations.

So, how can a speaker of English sound-out "Ａを心配させるな" in English?

Perhaps:

1. "Do not cause yourself to be worried about A."

   OR

2. "Do not allow yourself to be worried about A (by some unspoken factor)." // but this is passive voice, not causative. Most certainly I don't even understand causative/passive to begin with.

Answer 1

Let us get the phrases straight if we want to discuss them.

You wrote 「Aを[心配]{しんぱい}かける」 twice, so I do not think it was a typo. The only correct particle to use in that expression is 「に」. 「を」 is not possible.

If you or anyone is unfamiliar with this usage of 「に」, I just happened to talk about it in another thread a few days ago. 君に話しがある How does this work?

So, the two expressions in question are:

Ａ[を]心配[させる]な。（Both 「を」and「に」are possible.）

Ａ[に]心配[かける]な。（Only「に」 is possible.）

These two basically mean the same thing even though they are structured differently. They both mean:

"Do not make A feel uneasy.", "Do not give A anxiety.", etc.

Since I am a Japanese-speaker, I shall let you and others form your own English translations that satisfy your needs. The phrases do not mean anything far from what I said above, though.
