I definitely wouldn't say it's a bad translation, but some parts are incorrectly parsed. For instance, the line 赤く染まってく血の海が流れ　続けて刹那に誓った約束を　果たし心無き者を消し去り the first 続けて is still connected to the previous line, so the parsing would be like so: 赤く染まってく血の海が流れて続けて、刹那に誓った約束を果たし、心無き者を消し去り. 果たし and 消し去り, since they are the verb stem minus the masu, is just like saying 果たして and 消し去って. So in English these lines would be somewhat like: The sea/ocean that's stained with red blood continues to flow. The promise I swore on (for a moment/short period of time) has been carried out, and I eradicate those with no heart (the 無き者 here could also refer to a dead person, but I decided to go with 'those with no heart' since she's avenging her dead sister)
