Why is the Pasuk that the Haggadah uses to show that “the Egyptians did bad to us" the Passuk in which Pharaoh sits down and says (Shemos 1:10):
הָ֥בָה נִֽתְחַכְּמָ֖ה ל֑וֹ פֶּן־יִרְבֶּ֗ה וְהָיָ֞ה כִּֽי־תִקְרֶ֤אנָה מִלְחָמָה֙ וְנוֹסַ֤ף גַּם־הוּא֙ עַל־שֹׂ֣נְאֵ֔ינוּ וְנִלְחַם־בָּ֖נוּ וְעָלָ֥ה מִן־הָאָֽרֶץ׃
Let us deal shrewdly with them, so that they may not increase; otherwise in the event of war they may join our enemies in fighting against us and rise from the ground.”
Nothing bad really happens in that Passuk. Why not use an example of the Egyptians giving us backbreaking useless labor, throwing the baby boys in the river, or even [if you can use a Midrash] (Midrash Rabbah 1:34) slaughtering 150 Jewish children twice a day and bathing in their blood?
Additionally this is supposed to be an example of the Egyptians doing bad to us. This is just Pharaoh himself talking.
