The pathetic part is the context itself. One thing is falling in a situation where you can't do anything, because you simply can't. (Falling in said situation by helping other ppl is in this category too)and another different thing is falling in said situation because of your own fault and not being able to do anything about it. And asking for help is understandable, but it's kinda meh when you risk a friends life because of that.
However, Sanji felt on said trap because of his simpness, he can't do anything about it because he doesn't want to, and crying out for help is literally doing what the enemy wanted, aka making your friend appear allowing the enemy to catch him/her easier (a friend that is being chased by every-fucking-one mind you). Everything ended up fine, but imagine for a split second that they managed to capture Robin because of Simpji. Either BM defeated her or they gang banged her. That's what makes this pathetic, putting your friend in a very risky situation because you can't help your own ass after being the one who screwed up everything. Messing everything and calling a friend to wipe your mess is awful. Said it once, and I will say it twice, asking for help isn't being pathetic. Context matters.
