Putin killed Navalny doesn't necessarily means that he gave order. It is just can be like he was tortured and some jailer overdid it. Often we are trying to find big reasons were its just a mess.

This impression can only arise if you are not familiar with the situation or if you were already a supporter of putin beforehand. putin said so many stupid things in this interview that it is hard for me to understand how it could have been overlooked.
