What is the purpose of Ti role?

[Delilah]

I have sometimes wondered what the point of Ti role in EII is? How can it be / be made to be a useful thing? I have noticed that ILEs, for instance, are exceedingly good at making use of various laws and legal complexities, like even to the extent of employing lawyers, police and negotiators in civil matters and matters of property/ownership, something which I personally see as either too severe or too serious to bring down on someone just like that. Yet, the ILE i know who made use of these systems went on to successfully protect their own interest in this case.

Something like FI humanity holds me back in cases of protecting my own self interest, yet could Ti tie in with Fi somehow without having to end up needing SE and *without* violating Fi?

Does Ti role in ESI work any differently than in EII?
