well. i would personally argue about whether or not it was ic for the character to carry it out like this, myself.
there's actually a situation in fate/zero similar to the one that was played out here where caster murders several children in order to get saber to admit she's jeanne. he does it by bringing the children directly to her and threatening/murdering them in front of her instead of making a public spectacle out of it. he doesn't exactly try very hard to cover his tracks which causes another character to catch on to what he's doing, but it is very clearly meant to be set up for saber only.
so yeah. caster contacting robin privately would have actually matched his canonical modus operandi better and would have been more comfortable for the rest of the game. it would have made for a situation that would have allowed for 'rescuer' characters to opt into the plot but the rest of the game could ignore.
also keep in mind that due to confusing communication, it was repeatedly implied that there would be more broadcasts like this one. after a while, if your character had close contact with robin or any of the victims you would really have to push it to ignore this plot, which is seriously uncomfortable.
honestly, nobody is saying that these plots aren't allowed. i would personally compare it to juggling. in a standard plot, you're juggling with soft, foam balls, so you can do whatever you want, really. you could juggle right in the middle of a crowd. if you miss a ball or accidentally throw it at someone the worst you'll have to deal with is them getting annoyed.
in a plot that involves sensitive material, you're juggling knives or chainsaws or something, which looks really cool if you pull it off right but you have to be way more careful about it. you need to have a lot of space around you so you don't actually hurt anyone, and other people involved in your act should be people who you know can handle a thing like this.
