I just want to note here for readers that the following isn’t correct (but you’ve already made a clarifying comment, so I realise you know this):
In total uti (in the human world), it is okay to:
kill someone, provided that by doing so you bring into the world another human with the same happiness.
Total uti only says this is ok if you leave everything else equal (in terms of total utility). In almost all natural situations you don’t: killing someone influences the happiness of others too, generally negatively.
